feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT
headers don't compile as C++), -lcombase dropped, a reference leak fixed.
- project.cpp honours --local for Crafter.Event, Math and Asset, as Asset
does for Math, and builds every test through one helper, projectArgs
included.
- Tests: DebugMessengerSeverity, DeletionQueueThreads, DeviceSelection,
HeapSlotReuse, MeshLifetime, MipChainNonSquare, PipelineLifetime,
RTPassPushData, SwapchainTransferDst, UploadInFlight, VulkanBufferAddress,
VulkanShaderLifetime, WindowUpdateClock; others extended.
Breaking: SaveFrame is CaptureNextFrame; Mesh::opaque is geometryFlags; a
buffer without SHADER_DEVICE_ADDRESS usage has no address; frameCounter is
std::atomic.

RTPassPushData, SwapchainTransferDst, UploadInFlight, VulkanBufferAddress,
VulkanShaderLifetime, WindowUpdateClock; others extended.
Breaking: SaveFrame is CaptureNextFrame; Mesh::opaque is geometryFlags; a
buffer without SHADER_DEVICE_ADDRESS usage has no address; frameCounter is
std::atomic.

feat(device): applications ask for the device features their shaders use
Device
- Device::Initialize(required, optional) takes DeviceFeatures, the five
core feature structs vulkan10 to vulkan14. The library enables only what
its own shaders and code use. Device::enabledFeatures says what was
enabled, supportedFeatures what the GPU has, apiVersion the version in
use.
- shaderInt16, shaderFloat16, storageBuffer16BitAccess, scalarBlockLayout
and the uniform-buffer, storage-buffer and storage-image non-uniform
indexing bits are no longer enabled for everyone. An application whose
shaders take uint16_t spec constants passes
{.vulkan10 = {.shaderInt16 = VK_TRUE}}. scalarBlockLayout stays on with
the NVIDIA workaround, whose TLAS address may sit in a struct's tail
padding.
- Every GPU is weighed before one is chosen: Vulkan 1.3, the swapchain and,
below 1.4, maintenance5 extensions, the library's needs, the required
features. One that can't run the application is skipped, saying why when
it ranks higher. A CPU device runs it only when nothing else is listed,
and CRAFTER_GRAPHICS_DEVICE never falls back. A GPU two drivers both list
is tried through each.
- When no GPU qualifies, Initialize throws naming each GPU's gaps. It
destroys the instance it made, before any Wayland connection, so it can
be called again asking for less.
- maintenance5 is vulkan14's on a 1.4 GPU and VK_KHR_maintenance5's below.
CRAFTER_GRAPHICS_NO_VULKAN_1_4 runs as a 1.3 application, to exercise
that path on a 1.4 GPU.
- VK_KHR_spirv_1_4 and VK_KHR_shader_float_controls, core since 1.2, are no
longer enabled, nor VK_EXT_shader_atomic_float, which was enabled without
its feature struct. memoryDecompression's feature bit is queried before
it is enabled.
Shaders
- VulkanShader checks a module's capabilities, declared directly or
implicitly, against the enabled core features, the GPU's subgroup
operations and the optional groups, and throws naming the field to pass,
or saying the GPU lacks it. The tables are generated from vk.xml and
SPIR-V's grammar.
- WorkaroundNvidiaAS::Patch sized a row-major matrix push member by its
columns, so the TLAS address could land inside it.
Window
- The swapchain format is one whose own feature flags allow storage reads
and writes without a format, which since Vulkan 1.3 each format says for
itself; shaderStorageImageRead/WriteWithoutFormat are no longer required.
Tests
- DeviceFeatures: ResolveFeatures, ChooseDevice and CheckShaderCapabilities,
without a GPU.
- FeatureRequests: required and optional features end to end, the 1.3
path, and a retry after a refusal.
- PushConstantRewrite: a row-major mat3x4 push member.
- HeapASRead, HeapDynamicIndexHit, RTPassPushData and the ray-tracing
examples ask for the features their shaders use.

Device::Initialize required twelve device extensions with no capability
check. Mesa Turnip (Adreno) lacks six of them: VK_EXT_descriptor_heap,
VK_KHR_shader_untyped_pointers, VK_EXT_device_fault and the three ray
tracing extensions. vkCreateDevice failed there, so not even a UI-only
program could start, although the UI path is compute-only and needs
nothing else that Turnip is missing.
The descriptor heap, ray tracing and device fault are now optional
groups, detected at start-up from the extension list and the feature
bits (Device::descriptorHeapSupported, rayTracingSupported,
deviceFaultSupported). Ray tracing needs the heap; on a device without
it the ray tracing entry points throw a message naming the cause.
Without the heap the same bindless slots live in one update-after-bind
descriptor set per frame, owned by DescriptorHeapVulkan: binding 0
storage images, 1 sampled images, 2 samplers, 3 storage buffers. Slot
allocation, the slot handles, UIDispatchHeader and the UIRenderer API
are unchanged; buffer slots simply stop being offset. Window::Render
binds that frame's set where it binds the heap, every compute pipeline
shares the heap object's pipeline layout, and push data travels as push
constants.
Each UI kernel is built twice from one source. ui-shared.glsl declares
its resources through UI_HEAP_* macros that expand to descriptor_heap
or, with CRAFTER_GRAPHICS_DESCRIPTOR_SETS defined, to set/binding.
<name>.comp.spv and <name>.comp.sets.spv ship side by side and
ComputeShader::Load picks one. The heap build of every shader is
byte-identical to before.
Breaking:
- ComputeShader::Load takes the heap as a second argument.
- DescriptorHeapVulkan is no longer copyable or movable.
- Custom UI shaders declare heap resources with the UI_HEAP_* macros
and are registered twice in project.cpp (see the README).
- project.cpp uses Shader::defines and Shader::variant, so it needs a
crafter-build that has them (Crafter.Build master, fe38cc1 or later).
Also:
- maintenance5 is enabled as a feature, not only as an extension:
every VulkanBuffer already relied on VkBufferUsageFlags2CreateInfo.
- Barrier stage masks drop RAY_TRACING_SHADER on devices without ray
tracing, and ImageVulkan::Create resolves its default consumer stage
to COMPUTE_SHADER there.
- Window refuses a swapchain whose image count is not numFrames
instead of writing past images[]. The limitation itself is #160.
- CRAFTER_GRAPHICS_NO_DESCRIPTOR_HEAP forces the fallback on a driver
that has the heap, so it can be exercised on a desktop GPU.
Verified on an RTX 4090 in both modes under the validation layer, and
on a Fairphone 6 (Turnip, Adreno 810, postmarketOS), where the fallback
is the only path.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT
headers don't compile as C++), -lcombase dropped, a reference leak fixed.
- project.cpp honours --local for Crafter.Event, Math and Asset, as Asset
does for Math, and builds every test through one helper, projectArgs
included.
- Tests: DebugMessengerSeverity, DeletionQueueThreads, DeviceSelection,
HeapSlotReuse, MeshLifetime, MipChainNonSquare, PipelineLifetime,
RTPassPushData, SwapchainTransferDst, UploadInFlight, VulkanBufferAddress,
VulkanShaderLifetime, WindowUpdateClock; others extended.
Breaking: SaveFrame is CaptureNextFrame; Mesh::opaque is geometryFlags; a
buffer without SHADER_DEVICE_ADDRESS usage has no address; frameCounter is
std::atomic.

fix(win32): restore mouse moves, add enter and leave, capture drags, and close and destroy windows cleanly
Win32
- WM_MOUSEMOVE is handled again: c9ebd44 put the WM_CHAR case where it
was, so currentMousePos stopped following the mouse and onMouseMove
never fired. Positions are read signed (GET_X_LPARAM), since under
capture they run past the client area.
- onMouseEnter and onMouseLeave. The first move over the client area
after a leave is the enter, and arms the TME_LEAVE whose WM_MOUSELEAVE
is the leave. An enter counts only once that is armed, a leave only
after an enter, and a move past the client area is a move only.
- A press captures the mouse, so a drag that leaves the window still
sends its moves and its release, as Wayland's implicit grab does.
Losing the capture releases what is held, and a button-up without its
press fires nothing.
- WM_CLOSE fires onClose and clears open, as xdg_toplevel.close does,
instead of destroying the HWND under the swapchain. WM_DESTROY no
longer posts WM_QUIT, which nothing read.
- ~Window detaches the HWND and destroys it. It stayed on screen, and its
messages went to the freed Window. WndProc hands messages without a
Window to DefWindowProc, and looks the Window up again after an event
that more work follows, in case a listener destroyed it.
- The constructor's message pump leaves input queued for StartSync: the
WM_MOUSEMOVE sent when a window appears under the cursor made an
onMouseEnter nobody could hear yet. The mouse state is reset before
the platform code, no longer after it.
- A window after the first finds its class registered, which showed an
error box.
- The wheel remainder is the window's, no longer a function static that
every window shared, and a leave drops it.
Window
- PointerEnter, PointerMove, PointerLeave and PointerScroll hold the rules
both native backends report the pointer by. An enter puts the entry
position in currentMousePos before onMouseEnter fires, and is followed
by a move, on Wayland too now. scrollRemainder replaces
Device::scrollDetentRemainder, and mouseInside is shared.
Tests
- PointerEnterLeave: enter, move and leave through the wl_pointer
callbacks.
- PointerWin32: posts a real HWND the messages above and pumps them as
StartSync does. Built for x86_64-w64-mingw32 it runs under Wine, and is
skipped where Wine is not on PATH.

fix(window): set the title on Win32 through a Unicode window class, and send only the view's bytes on Wayland
Win32
- SetTitle had a body only for Wayland, so the title passed to Window's
constructor and every later SetTitle left a Win32 window untitled. It
converts the title from UTF-8 and hands it to SetWindowTextW.
- The window class is registered with RegisterClassW, the window made
with CreateWindowExW, and WndProc hands what it does not handle to
DefWindowProcW. An ANSI class has the text of every message converted
to the process code page on its way to WndProc, so SetWindowTextW
alone would not do: under Wine, in CP1252, 日本 in a title came back
as ??. WM_CHAR, whose handler takes wParam for a UTF-16 code unit, got
€ as its CP1252 byte 0x80 and passed it on as U+0080, and 日 and both
halves of a surrogate pair as ?.
- Both message pumps use PeekMessageW and DispatchMessageW. PeekMessageA
converts WM_CHAR to the code page whatever the window's class: on the
Unicode class, an ANSI pump still turned 日 and the surrogates into ?.
Wayland
- SetTitle handed title.data() to xdg_toplevel_set_title, which reads up
to a NUL: a view into a longer string sent the whole string, and an
empty view's null data() made libwayland fail the display with EINVAL.
It copies the view into a std::string, as SetAppId does.
Tests
- TextWin32: the constructor's title, SetTitle with characters outside
the code page, with a view into a longer string and with an empty
title, read back with GetWindowTextW; and é, €, 日 and a surrogate
pair posted as WM_CHAR and delivered by StartSync's own loop, which
returns on the WM_CLOSE posted after them, so a StartSync pumping with
the A functions fails it. The window is disabled, so a real keystroke
can't reach the check. Without the fix every check but the empty title
fails. Like PointerWin32, built on Linux it runs under Wine.
- TitleWayland: SetTitle's set_title requests, read off a wl_display
connected to a socketpair, for a view into a longer string and for an
empty view. Both checks fail without the fix. No compositor.
- PointerWin32 pumps with the W functions, as StartSync now does.
Docs
- AGENTS.md names TextWin32 beside PointerWin32 as the Win32 tests, says
what their Wine runs needed (the vulkan-1 import library, -luuid, which
the link flags lack, #184, and a __libc_single_threaded definition),
and lists TitleWayland among the tests that need no GPU.

The refit and rebuild barriers cover compute ray queries too.

and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.

feat(window): multi-frame-in-flight frame pacing (#40)
The renderer was effectively single-buffered despite allocating
triple-buffered infrastructure: Render() ended with an unconditional
vkQueueWaitIdle, and a single (presentComplete, renderComplete)
semaphore pair with zero fences was shared for the Window's lifetime.
Rework the pacing model so up to numFrames frames overlap:
- Per-swapchain-image VkFence, signaled by the submit and waited+reset
before that image's command buffer / descriptor-heap slot is
re-recorded. Keyed by acquired image index (drawCmdBuffers, the heap
slots, and the swapchain images are all image-indexed — see
WriteSwapchainDescriptors). Created signaled so first use passes.
- Per-image render-finished (present) semaphore: the presentation engine
holds it until the image is re-acquired, so per-image is the only safe
key (per-CPU-frame trips VUID-vkQueueSubmit-pSignalSemaphores-00067).
- Per-CPU-frame acquire semaphores (image index unknown until acquire
returns), sized numFrames+1: in-flight depth is bounded by the
per-image fences, so numFrames+1 distinct acquire semaphores guarantee
the reused one has no pending op (VUID-vkAcquireNextImageKHR-01779).
- Drop the steady-state vkQueueWaitIdle; keep it on resize / OUT_OF_DATE
/ teardown.
Add tests/FrameLoopSync: drives the real frame loop against a live
Wayland compositor for 60 frames (>> in-flight slots) and asserts the
CPU frame counter advanced, the swapchain rotated across multiple
images, and the validation layer stayed silent — the load-bearing check,
since the old single-pair design only avoided being an active race
because the wait-idle masked it.

fix(win32): restore mouse moves, add enter and leave, capture drags, and close and destroy windows cleanly
Win32
- WM_MOUSEMOVE is handled again: c9ebd44 put the WM_CHAR case where it
was, so currentMousePos stopped following the mouse and onMouseMove
never fired. Positions are read signed (GET_X_LPARAM), since under
capture they run past the client area.
- onMouseEnter and onMouseLeave. The first move over the client area
after a leave is the enter, and arms the TME_LEAVE whose WM_MOUSELEAVE
is the leave. An enter counts only once that is armed, a leave only
after an enter, and a move past the client area is a move only.
- A press captures the mouse, so a drag that leaves the window still
sends its moves and its release, as Wayland's implicit grab does.
Losing the capture releases what is held, and a button-up without its
press fires nothing.
- WM_CLOSE fires onClose and clears open, as xdg_toplevel.close does,
instead of destroying the HWND under the swapchain. WM_DESTROY no
longer posts WM_QUIT, which nothing read.
- ~Window detaches the HWND and destroys it. It stayed on screen, and its
messages went to the freed Window. WndProc hands messages without a
Window to DefWindowProc, and looks the Window up again after an event
that more work follows, in case a listener destroyed it.
- The constructor's message pump leaves input queued for StartSync: the
WM_MOUSEMOVE sent when a window appears under the cursor made an
onMouseEnter nobody could hear yet. The mouse state is reset before
the platform code, no longer after it.
- A window after the first finds its class registered, which showed an
error box.
- The wheel remainder is the window's, no longer a function static that
every window shared, and a leave drops it.
Window
- PointerEnter, PointerMove, PointerLeave and PointerScroll hold the rules
both native backends report the pointer by. An enter puts the entry
position in currentMousePos before onMouseEnter fires, and is followed
by a move, on Wayland too now. scrollRemainder replaces
Device::scrollDetentRemainder, and mouseInside is shared.
Tests
- PointerEnterLeave: enter, move and leave through the wl_pointer
callbacks.
- PointerWin32: posts a real HWND the messages above and pumps them as
StartSync does. Built for x86_64-w64-mingw32 it runs under Wine, and is
skipped where Wine is not on PATH.

fix(window): set the title on Win32 through a Unicode window class, and send only the view's bytes on Wayland
Win32
- SetTitle had a body only for Wayland, so the title passed to Window's
constructor and every later SetTitle left a Win32 window untitled. It
converts the title from UTF-8 and hands it to SetWindowTextW.
- The window class is registered with RegisterClassW, the window made
with CreateWindowExW, and WndProc hands what it does not handle to
DefWindowProcW. An ANSI class has the text of every message converted
to the process code page on its way to WndProc, so SetWindowTextW
alone would not do: under Wine, in CP1252, 日本 in a title came back
as ??. WM_CHAR, whose handler takes wParam for a UTF-16 code unit, got
€ as its CP1252 byte 0x80 and passed it on as U+0080, and 日 and both
halves of a surrogate pair as ?.
- Both message pumps use PeekMessageW and DispatchMessageW. PeekMessageA
converts WM_CHAR to the code page whatever the window's class: on the
Unicode class, an ANSI pump still turned 日 and the surrogates into ?.
Wayland
- SetTitle handed title.data() to xdg_toplevel_set_title, which reads up
to a NUL: a view into a longer string sent the whole string, and an
empty view's null data() made libwayland fail the display with EINVAL.
It copies the view into a std::string, as SetAppId does.
Tests
- TextWin32: the constructor's title, SetTitle with characters outside
the code page, with a view into a longer string and with an empty
title, read back with GetWindowTextW; and é, €, 日 and a surrogate
pair posted as WM_CHAR and delivered by StartSync's own loop, which
returns on the WM_CLOSE posted after them, so a StartSync pumping with
the A functions fails it. The window is disabled, so a real keystroke
can't reach the check. Without the fix every check but the empty title
fails. Like PointerWin32, built on Linux it runs under Wine.
- TitleWayland: SetTitle's set_title requests, read off a wl_display
connected to a socketpair, for a view into a longer string and for an
empty view. Both checks fail without the fix. No compositor.
- PointerWin32 pumps with the W functions, as StartSync now does.
Docs
- AGENTS.md names TextWin32 beside PointerWin32 as the Win32 tests, says
what their Wine runs needed (the vulkan-1 import library, -luuid, which
the link flags lack, #184, and a __libc_single_threaded definition),
and lists TitleWayland among the tests that need no GPU.

fix(window): size the swapchain for its present mode, and key frames in flight by frame instead of image
Window
- CreateSwapchain asked for exactly numFrames (3) images whatever the
surface said, read them into a three-element array, and keyed the
command buffers, the fences and the descriptor-heap copy holding "its"
swapchain image by the acquired image index. A swapchain of another
size fell back to FIFO (asked for MAILBOX or IMMEDIATE) or threw, and a
surface whose minimum is above three got a create info below it
(#160). Mesa's MAILBOX needs four images: Turnip on phoc, llvmpipe on
any Wayland compositor.
- The present mode is picked first, then the swapchain is sized by
SwapchainCapabilities: the surface's counts for that mode where the
instance has surface_maintenance1. With swapchain_maintenance1 the
swapchain names its mode (VkSwapchainPresentModesCreateInfoKHR), which
is what makes the mode's own count the one that applies, at creation and
to the forward progress of a UINT64_MAX acquire; without it the stricter
of the mode's and the surface's counts for all modes. It asks for
numFrames or that minimum where more, never past the maximum
(SwapchainMinImageCount). Turnip's FIFO keeps its three images and
MAILBOX gets four. The FIFO fallback and presentModeUnfit are gone.
- images, imageViewInfos (was imageViews: they are create-infos), the made
imageViews that descriptor sets take, imageInitialised and the
render-finished semaphores are per image, as many as the driver made.
The views are made once per swapchain. The semaphores only grow, since
a present of the old swapchain may still wait on one.
- Frames in flight stay numFrames, keyed by currentFrame, frameCounter %
numFrames: the command buffer, the fence, the acquire semaphore, the
heap copy (or set), RenderingElement3D::tlases, the frameIdx a pass is
recorded with. currentImage is the acquired image. currentBuffer is
gone, so code that used it stops compiling instead of picking the wrong
one; RenderPass::Record's frameIdx keeps its name and is now the frame
slot, as RenderPass.cppm says.
- The frame's fence is waited before the acquire. The acquire semaphores
need no spare then, and a frame waits for exactly the one numFrames
before it, which the deletion queue and the staging rings count on and
fences keyed by image did not promise once images come back out of
order. The swapchain slots are written before the fence is reset.
- From the acquire to the present the window is recording: a Resize or
SetPresentMode from a listener (a VSync key ticked in onUpdate) takes
effect after the present, through RebuildSwapchain, together with a
present that found the swapchain out of date. Rebuilding mid-frame used
to destroy the image the frame was drawing into; with images sized per
swapchain it would also index past the new one's end.
DescriptorHeapVulkan
- Frames and images pair up differently from frame to frame, so no heap
copy can keep one swapchain image. AddSwapchainSlot(slot, window) lists
an image slot as that window's swapchain image, and Window::Render
writes the image a frame acquired into its window's listed slots in that
frame's copy, or its set, before onUpdate, skipping a slot that holds it
already. A slot is one window's, so two windows can share a heap without
writing each other's slots under each other's frames in flight. A slot
listed during a frame its window records is written at once. A slot past
the heap's image slots, an empty ImageSlot's 0xFFFF among them, is
refused. Freeing a slot unlists it, as does initialising the heap in
either binding model. WriteImageSet, the one use of which this
replaces, is gone, and with it the per-frame dimension of setImageViews.
Device
- VK_KHR_surface_maintenance1 (or EXT) and VK_KHR_get_surface_capabilities2
are enabled where the loader has them (surfaceMaintenance1Supported,
vkGetPhysicalDeviceSurfaceCapabilities2KHR), and the matching
swapchain_maintenance1 with its feature where the device has it
(swapchainMaintenance1Supported).
- DistinctGpus groups the physical devices by GPU as CRAFTER_GRAPHICS_DEVICE
numbers them, for ChooseGpu and tests.
UI
- UIRenderer lists its output slot instead of writing every copy itself,
and again on every resize; the resize listener is gone on both
backends. The headers' frameIdx is currentFrame.
Examples
- VulkanTriangle, Sponza, SponzaBench and RTVolume list their output slot
and write only the per-frame TLASes. They wrote imageViews[f] into copy
f once, which a resize left pointing at destroyed images.
Tests
- SwapchainImageCount: SwapchainMinImageCount on the numbers drivers
report; every offered mode keeps its mode and gets what the window asks
for; every frame presents the colour it drew, read back a texel per
frame; a switch and a resize asked for during a frame wait for its
present; a slot listed during a frame holds its image at once; two
windows on one heap draw their own colours. The frame checks run again
in child processes, through CRAFTER_GRAPHICS_DEVICE, on a GPU whose
swapchains have more images than frames (this one, else llvmpipe), in
each binding model the parent didn't cover; a child skips only for a GPU
that can't run the library, and checks it runs the model it was asked
for.
- FrameLoopSync checks the frame slot follows the frame counter and counts
the swapchain's own images. HeapASRead, HeapDynamicIndexHit and
RTPassPushData list their swapchain slot and drop their resize rewrites.
Docs
- README, AGENTS.md and AGENTS.consumer.md: frames and images, the
swapchain slots, rebuilds held to the present, the new optional groups.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT
headers don't compile as C++), -lcombase dropped, a reference leak fixed.
- project.cpp honours --local for Crafter.Event, Math and Asset, as Asset
does for Math, and builds every test through one helper, projectArgs
included.
- Tests: DebugMessengerSeverity, DeletionQueueThreads, DeviceSelection,
HeapSlotReuse, MeshLifetime, MipChainNonSquare, PipelineLifetime,
RTPassPushData, SwapchainTransferDst, UploadInFlight, VulkanBufferAddress,
VulkanShaderLifetime, WindowUpdateClock; others extended.
Breaking: SaveFrame is CaptureNextFrame; Mesh::opaque is geometryFlags; a
buffer without SHADER_DEVICE_ADDRESS usage has no address; frameCounter is
std::atomic.

fix(font-atlas): give glyphs that find no room a cell when the next frame begins, evicting the least recently drawn
The atlas packed glyphs onto shelves and never gave a place back (#55).
Once its 1024x1024 image was full, EnsureAndGet returned nullptr for each
new glyph before caching anything, so every new string holding one
rasterised it again, and ShapeText dropped it together with its advance:
the rest of the line closed up over the gap, and stayed that way.
FontAtlas
- A glyph is measured, not rasterised, until it gets a cell. One that
finds no free room keeps its advance and box and draws blank for a
frame. EnsureAndGet always returns the glyph, now a reference;
Glyph::Resident() says whether it has a cell, Glyph::handle which one
(slot and generation).
- Evictions wait for the next frame: its first EnsureAndGet, Touch or
Update places the glyphs that waited, once every glyph the frame before
drew has been marked. Evicting while a frame is still asking for glyphs
took ones it drew further down, which then took others in turn: a page
switched back to could rasterise most of itself again rather than what
it was missing, and on the DOM backend an over-full view could do so
every frame.
- A glyph keeps its cell for framesInFlight + 1 frames after it was drawn.
The frame loop waits frame u's fence at the start of frame
u + framesInFlight, but Device::frameCounter reads that from the end of
the frame before, and input callbacks and onBeforeUpdate run in between.
- FontAtlas::Packer places glyphs. Until the rows run out it fills shelves
exactly as before. Then a glyph takes the same columns of one shelf at
least as tall, or of several in a row as tall together, the free rows
below the last shelf counting as one more: free texels, and, when the
frame begins, glyphs nothing in flight draws, the least recently drawn
first. A glyph spanning shelves lets in one taller than every shelf, and
a few glyphs drawn every frame pin only their columns. Merging whole
shelves instead, tried first, left a random workload without room for a
glyph while a median 43% of the atlas was in flight; spanning, at 65%.
- A box that found no room in a frame is remembered, with every box at
least as big, as a small set per mode, until the frame ends or (without
eviction) something is evicted: a saturated atlas no longer searches
every shelf for each of its missing glyphs.
- An evicted glyph is forgotten, and its texels are zeroed and uploaded
with the glyph that takes its place: a neighbour's filtering at its edge
must read padding or zero, not a stale glyph.
- Touch(handles) marks every glyph whose handle still holds its cell, and
says whether all did. InvalidateFont(font) forgets the font's glyphs and
those waiting for a cell, whose Font* the next frame would read. The
glyph index is looked up at rasterisation, so a Font replaced in place
never gets one past its glyphs. GlyphsRasterized() counts, for tests.
UIRenderer
- A shaped run keeps a handle per glyph it draws. A hit touches them all,
so the atlas keeps what is drawn every frame, and shapes the run again
when one was evicted or one had no room. A glyph without room draws
blank but advances the pen.
- InvalidateFont clears the atlas's glyphs of the font too, as its comment
and AGENTS.md always said it did.
- Record calls the atlas's Update before onBuild, every frame, so the
waiting glyphs are placed and uploaded first. Dispatch uploads the atlas
before any kernel, a Tier 1 one sampling FontAtlasImageSlot() included:
a glyph placed earlier in onBuild can sit in a cell another glyph had.
DispatchText and DispatchFused no longer do it themselves.
Device, Window (DOM)
- Device::frameCounter and Device::framesInFlight exist on the DOM backend
too, the counter bumped at the end of Window::Render, with one frame in
flight: a frame's writeTexture lands before that frame's submit but after
every earlier one.
HelloUI
- One set of item buffers and slots per frame in flight, by frameIdx. A
frame still on the GPU read the items the next frame's onBuild was
rewriting; with cells changing hands, those can name cells it drew other
glyphs in.
Tests
- FontAtlasPacker: the packer with made-up boxes and no device: the fill
order, least recently drawn first, framesInFlight + 1 frames held,
nothing without evict, wide glyphs, tall glyphs spanning shelves and the
free rows, Touch past a stale handle, stale handles, dirty spans, and the
invariants over a random workload placed the way the atlas places.
- FontAtlasEviction: fills the atlas through ShapeText frame by frame. The
line that no longer fits keeps its advance and its glyphs' places; its
missing glyphs aren't rasterised while nothing can go; when only line 0
is cold, only its glyphs give way; a frame's own misses evict nothing in
it; a frame later the line and twenty more are whole, pixel for pixel,
line 0 losing a larger share than the glyphs drawn after it; a stale
cached run is shaped again; no stale texel is left; InvalidateFont
reaches the atlas. Against master, with its two calls to the new API
stubbed out, an earlier version failed ten checks.
- UIDispatchAtlasFlush: a custom ui.Dispatch after ShapeText leaves the
atlas uploaded. Needs a compositor.
- ShapeTextCache: a hit rasterises nothing; after InvalidateFont the
re-shaped run draws the same, from new cells.
Docs
- README and AGENTS.consumer.md: the atlas's eviction, the frame a glyph
waits, shaping text every frame into per-frame item buffers,
InvalidateFont, EnsureAndGet's signature and Lookup's lifetime, and that
the atlas, like the deletion queue, assumes one rendering window and
evicts nothing without one.
- AGENTS.md: FontAtlas::Packer among the pure-logic helpers, eviction
without a Window, and InvalidateFont.
Breaking: FontAtlas::EnsureAndGet returns const Glyph& and never fails;
check Glyph::Resident() before drawing from its UVs. FontAtlas::Touch is
no longer noexcept. A GlyphItem is good for the frame it was shaped for,
once the atlas has filled up, and item buffers must be per frame.

fix(ui): decode the font atlas's SDF in atlas pixels, so text edges ramp over one screen pixel
Shaders
- ui-text and ui-fused turned a sample of the R8_UNORM atlas into a
distance with (128/255 - sdf) * 32. stb_truetype writes kOnEdgeValue +
kPixelDistScale * distance into each byte, so an atlas pixel is
kPixelDistScale / 255 of a sample; 32 made every distance 1024/255
(about 4) times too large, and the coverage ramp, meant to span one
screen pixel, spanned a quarter of one: nearly every edge pixel came out
fully on or fully off, and text looked pixelated at every size. On an
RTX 4090, UIFallbackParity's 22 px label had 98 partly covered pixels
where stb_truetype's own rasterizer has 415. Wrong since the v3 UI
(1f56973), and copied into the fused kernel (574242d).
- The decode now lives once, in ui-shared.glsl: UI_SDF_ON_EDGE and
UI_SDF_PIXEL_DIST_SCALE are FontAtlas's two constants in the encoder's
own units, uiSdfDistance decodes a sample, uiGlyphRamp works out a
glyph's ramp when it is loaded and uiGlyphCoverage the coverage per
pixel. Both kernels call them, and a copy of either should; the UI_
prefix keeps them clear of a copied kernel's own names.
- stb_truetype truncates, so a byte b stands for [b, b + 1) of the encoded
value and the decode takes its middle: decoding b pulled every outline
1/64 atlas pixel inwards.
- The ramp is capped at what a byte holds, about 4 atlas pixels each way
of the outline. With the corrected decode a wider one left every glyph
quad's padding translucent below 4 px.
- The UV span is taken with abs(): a glyph turned by swapping its UVs got
a negative scale, a ramp of 0.0001 and hard edges.
- A glyph scaled differently along x and y ramps along the distance's
gradient, from two one-texel differences. With the corrected decode, one
width for both axes, the more minified one's, would leave a row stretched
three times with stems three pixels soft. Glyphs scaled alike, as
ShapeText's are, keep one multiply-add per pixel, the ramp's reciprocal
worked out with the glyph.
- The atlas size is queried rather than FontAtlas::kAtlasSize hard-coded
as 1024.
WebGPU
- The WGSL text kernel decoded the distance right but ramped over one
atlas pixel whatever the size: half a screen pixel at 16 px, two at
64 px. It now repeats ui-shared.glsl's decode, cap, abs and gradient
path, and renders TextAntialiasing's scene as Vulkan does (run through
Deno's WebGPU: 1.02, 1.07 and 1.09 times the reference's edge pixels,
where the old kernel gave 0.55, 2.19 and 0.89).
FontAtlas
- kOnEdgeValue and kPixelDistScale say the kernels carry copies of them.
Tests
- TextAntialiasing draws one string at 14 px, 64 px and 14 px stretched
three times, a 'g' turned by its UVs and empty atlas texels shrunk to
12.8 atlas pixels per screen pixel, through DispatchText and again
through DispatchFused, and holds them to stb_truetype's antialiased
rasterizer, to the mirror image and to nothing. On master the two plain
rows have 0.31 and 0.21 times the reference's edge pixels; with the
decode fixed alone the stretched row had 1.62 times, the turned 'g' was
127 codes off its mirror and the empty texels drew 48. Now: 1.02, 1.07
and 1.09 times, 0 and 0, on the 4090, on llvmpipe and on descriptor
sets. It skips a swapchain that isn't 8-bit, which the capture can't
read, and captures the first frame.
- FontAtlasDecode reads ui-shared.glsl and dom-webgpu.js and holds their
copies of the two constants to FontAtlas's. No GPU.
Docs
- AGENTS.consumer.md has a custom text shader decode through the helpers
and gives the encoding; README says so in a line; AGENTS.md lists the
tests and where the decode lives.

fix(window): size the swapchain for its present mode, and key frames in flight by frame instead of image
Window
- CreateSwapchain asked for exactly numFrames (3) images whatever the
surface said, read them into a three-element array, and keyed the
command buffers, the fences and the descriptor-heap copy holding "its"
swapchain image by the acquired image index. A swapchain of another
size fell back to FIFO (asked for MAILBOX or IMMEDIATE) or threw, and a
surface whose minimum is above three got a create info below it
(#160). Mesa's MAILBOX needs four images: Turnip on phoc, llvmpipe on
any Wayland compositor.
- The present mode is picked first, then the swapchain is sized by
SwapchainCapabilities: the surface's counts for that mode where the
instance has surface_maintenance1. With swapchain_maintenance1 the
swapchain names its mode (VkSwapchainPresentModesCreateInfoKHR), which
is what makes the mode's own count the one that applies, at creation and
to the forward progress of a UINT64_MAX acquire; without it the stricter
of the mode's and the surface's counts for all modes. It asks for
numFrames or that minimum where more, never past the maximum
(SwapchainMinImageCount). Turnip's FIFO keeps its three images and
MAILBOX gets four. The FIFO fallback and presentModeUnfit are gone.
- images, imageViewInfos (was imageViews: they are create-infos), the made
imageViews that descriptor sets take, imageInitialised and the
render-finished semaphores are per image, as many as the driver made.
The views are made once per swapchain. The semaphores only grow, since
a present of the old swapchain may still wait on one.
- Frames in flight stay numFrames, keyed by currentFrame, frameCounter %
numFrames: the command buffer, the fence, the acquire semaphore, the
heap copy (or set), RenderingElement3D::tlases, the frameIdx a pass is
recorded with. currentImage is the acquired image. currentBuffer is
gone, so code that used it stops compiling instead of picking the wrong
one; RenderPass::Record's frameIdx keeps its name and is now the frame
slot, as RenderPass.cppm says.
- The frame's fence is waited before the acquire. The acquire semaphores
need no spare then, and a frame waits for exactly the one numFrames
before it, which the deletion queue and the staging rings count on and
fences keyed by image did not promise once images come back out of
order. The swapchain slots are written before the fence is reset.
- From the acquire to the present the window is recording: a Resize or
SetPresentMode from a listener (a VSync key ticked in onUpdate) takes
effect after the present, through RebuildSwapchain, together with a
present that found the swapchain out of date. Rebuilding mid-frame used
to destroy the image the frame was drawing into; with images sized per
swapchain it would also index past the new one's end.
DescriptorHeapVulkan
- Frames and images pair up differently from frame to frame, so no heap
copy can keep one swapchain image. AddSwapchainSlot(slot, window) lists
an image slot as that window's swapchain image, and Window::Render
writes the image a frame acquired into its window's listed slots in that
frame's copy, or its set, before onUpdate, skipping a slot that holds it
already. A slot is one window's, so two windows can share a heap without
writing each other's slots under each other's frames in flight. A slot
listed during a frame its window records is written at once. A slot past
the heap's image slots, an empty ImageSlot's 0xFFFF among them, is
refused. Freeing a slot unlists it, as does initialising the heap in
either binding model. WriteImageSet, the one use of which this
replaces, is gone, and with it the per-frame dimension of setImageViews.
Device
- VK_KHR_surface_maintenance1 (or EXT) and VK_KHR_get_surface_capabilities2
are enabled where the loader has them (surfaceMaintenance1Supported,
vkGetPhysicalDeviceSurfaceCapabilities2KHR), and the matching
swapchain_maintenance1 with its feature where the device has it
(swapchainMaintenance1Supported).
- DistinctGpus groups the physical devices by GPU as CRAFTER_GRAPHICS_DEVICE
numbers them, for ChooseGpu and tests.
UI
- UIRenderer lists its output slot instead of writing every copy itself,
and again on every resize; the resize listener is gone on both
backends. The headers' frameIdx is currentFrame.
Examples
- VulkanTriangle, Sponza, SponzaBench and RTVolume list their output slot
and write only the per-frame TLASes. They wrote imageViews[f] into copy
f once, which a resize left pointing at destroyed images.
Tests
- SwapchainImageCount: SwapchainMinImageCount on the numbers drivers
report; every offered mode keeps its mode and gets what the window asks
for; every frame presents the colour it drew, read back a texel per
frame; a switch and a resize asked for during a frame wait for its
present; a slot listed during a frame holds its image at once; two
windows on one heap draw their own colours. The frame checks run again
in child processes, through CRAFTER_GRAPHICS_DEVICE, on a GPU whose
swapchains have more images than frames (this one, else llvmpipe), in
each binding model the parent didn't cover; a child skips only for a GPU
that can't run the library, and checks it runs the model it was asked
for.
- FrameLoopSync checks the frame slot follows the frame counter and counts
the swapchain's own images. HeapASRead, HeapDynamicIndexHit and
RTPassPushData list their swapchain slot and drop their resize rewrites.
Docs
- README, AGENTS.md and AGENTS.consumer.md: frames and images, the
swapchain slots, rebuilds held to the present, the new optional groups.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer

fix(wayland): open windows on compositors without xdg-decoration, viewporter or fractional scale
Window
- The constructor made a fractional scale, a toplevel decoration and a
viewport from Device::fractionalScaleManager, Device::manager and
Device::wpViewporter without looking at them. Device::handle_global
binds those globals only when the compositor advertises them, and
Initialize requires only wl_shm, wl_compositor and xdg_wm_base, so on a
compositor without one of the three (GNOME's Mutter has no
xdg-decoration) the constructor handed libwayland a null proxy and
crashed before the window existed (#162). Each object is now made only
when its global is there, which Resize and the destructor already
assumed.
- The fractional scale needs the viewporter too: the preferred scale is
applied through the viewport, which shows the buffer's physical pixels at
width/scale x height/scale. A surface without a viewport is as large as
its buffer, so there the scale stays 1, which keeps pointer and touch
positions, configure sizes and the text-input caret, all converted by
it, in physical pixels; the compositor scales the window up on a HiDPI
output. A scale that changes after the constructor is still applied only
by the next resize, which is #165.
- Without xdg-decoration the window has no title bar, since the library
draws no client-side decorations.
Device
- The optional globals say they are optional, and that a request on a
null proxy crashes.
Tests
- WindowOptionalGlobals: hides xdg-decoration, wp_viewporter and
wp_fractional_scale_v1 from the Window one at a time and all at once,
by nulling the Device statics after Initialize, and renders, resizes
and closes a window each time without a protocol error. Before the fix
it crashed on the window without xdg-decoration. A global the compositor
does not offer is reported as a SKIP line, since the path that uses it
goes untested there.
README
- Which Wayland protocols the window needs, and what it does without the
optional ones.

perf(text): cache shaped runs in ShapeText (#52)
ShapeText re-decoded UTF-8, re-looked-up every glyph, and recomputed
layout every frame for static strings (DrawText / EmitCenteredLabel run
inside per-frame onBuild). DrawText and EmitCenteredLabel also did a
second full pass over the glyphs to apply alignment.
Memoize the shaped run, keyed by (Font*, pxSize, color, utf8), as an
origin-relative vector<GlyphItem>. A cache hit skips decode/lookup/layout
and just translates the cached run into the output buffer by
(x + alignShift, baselineY). The alignment shift (Center = -advance/2,
Right = -advance) is folded into ShapeText's single pass, dropping the
second loop in both callers. TextAlign moves to the :UI partition so
ShapeText can take it.
Pure CPU memoization — the glyph buffer is fully rewritten and re-flushed
every frame, so a hit is byte-equivalent. A miss still calls Ensure so new
glyphs rasterise and dirty the atlas; hits don't (atlas entries are never
evicted). InvalidateFont drops a font's runs before it is destroyed (the
cache, like FontAtlas's glyph cache, keys on the Font pointer). A soft cap
bounds memory against pathological per-frame-unique text.
Adds the ShapeTextCache test (15 checks): hit == miss byte-for-byte, hits
don't touch the atlas, translate/alignment/truncation/InvalidateFont.

fix(rt): rebuild TLASes in place, after earlier traces, and queue their handles like a Mesh's
BuildTLAS
- A rebuild for a new instance count or build preference used to create a
new acceleration structure and destroy the old one at once, though the
command buffer being recorded could still use it (a scene and then a
model built in one setup). The acceleration structure now spans its whole
storage buffer, and a rebuild that fits builds into it again, so the
handle and tlases[i].address stay the same and nothing is destroyed. A
TLAS that outgrows its storage gets new storage and a new handle; the old
handle goes to the deletion queue ahead of the storage it lives in. It is
queued after the scratch is resized, and its address goes with it, so a
Resize or create that throws leaves no address of a queued acceleration
structure behind.
- The barrier before the build also orders earlier traces and compute ray
queries of the TLAS, which a refit or a rebuild in place would otherwise
overwrite while they read it (BuildTlasWriteBarrier). Its source access
mask holds no read bit: one does nothing, but makes synchronization
validation 1.4.363 report the second of two builds in one command buffer
as a write-after-write hazard.
- TlasReadBarrier is now TlasBarrier, shared by both barriers.
- Documented: call BuildTLAS once every earlier submission that used
tlases[index] has completed, and when the address stays the same.
TlasWithBuffer
- Moves hand the acceleration structure over, and destroying or assigning
over one queues it ahead of its storage. The implicit members dropped the
handle over freed storage, or left two owners and a moved-from TLAS that
refit through buffers it no longer had.
Tests
- TLASLifetime: destroying, moving, move-assigning and resetting a
TlasWithBuffer.
- TLASHighWaterMark skips without ray tracing. It asserts the acceleration
structure is rebuilt in place on a shrink or a growth within capacity,
that the old handle is queued before its storage on a growth past it, and
that builds in one command buffer keep the handle while they fit, queue
it once when one outgrows the storage, and free it only on its retire
frame.
- TLASBuildBarrier checks the barrier before the build too.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT
headers don't compile as C++), -lcombase dropped, a reference leak fixed.
- project.cpp honours --local for Crafter.Event, Math and Asset, as Asset
does for Math, and builds every test through one helper, projectArgs
included.
- Tests: DebugMessengerSeverity, DeletionQueueThreads, DeviceSelection,
HeapSlotReuse, MeshLifetime, MipChainNonSquare, PipelineLifetime,
RTPassPushData, SwapchainTransferDst, UploadInFlight, VulkanBufferAddress,
VulkanShaderLifetime, WindowUpdateClock; others extended.
Breaking: SaveFrame is CaptureNextFrame; Mesh::opaque is geometryFlags; a
buffer without SHADER_DEVICE_ADDRESS usage has no address; frameCounter is
std::atomic.

perf(tlas): dirty-track the per-frame TLAS instance+metadata upload (#118)
BuildTLAS rebuilt the host instance+metadata buffers with an O(n) copy of
every 64 B VkAccelerationStructureInstanceKHR + metadata entry every frame,
unconditionally, then flushed the whole high-water capacity (VK_WHOLE_SIZE)
on both buffers. At the millions-of-instances target that copy dominates the
CPU frame, and the whole-buffer flush costs on non-coherent BAR/VRAM.
Add a generation counter so only changed host-authored fields are copied, and
feed the same dirty span into the ranged FlushDevice(offset, bytes) overload:
- RenderingElement3D::hostDataVersion + MarkHostDataDirty() (bumps a global
monotonic counter). TlasWithBuffer::uploadedVersion records, per frame, the
version last copied into each slot. A slot is copied only when its element
advanced past the recorded version; version 0 ("untracked") reads dirty every
frame, so callers that don't opt in keep the prior copy-every-frame behaviour.
Globally-unique versions make this correct under relocation (Remove's
swap-and-pop, and remove+add that nets the same count on the refit path)
without tracking element identity. The reset on every topology change covers
buffer reallocation and the reshuffled element->slot mapping.
- The dirty [first, last] envelope drives both the copy and the flush: a new
VulkanBuffer::FlushDevice(cmd, access, stage, offset, bytes) overload flushes
+ barriers just that span for instanceBuffer, and the ranged
FlushDevice(offset, bytes) for metadataBuffer. When nothing is dirty both are
skipped — the skipped HOST->build barrier only ever ordered host writes, never
the application's compute-written GPU-owned transform (that compute->build
ordering is the caller's, and is unchanged).
Constraint honoured: transformOwnedByGpu transforms are still never host-copied.
The API field/method are mirrored on the WebGPU class for source portability
(the WebGPU build re-uploads its small mirror wholesale and ignores the version).
New test TLASInstanceDirtyTracking drives the real RT device and reads back the
host-mapped buffers to assert: tracked elements upload once then skip until
re-marked, untracked elements always upload, and relocation on the refit path
re-uploads exactly the moved slots — with zero validation-layer errors over the
ranged flush.

falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT
headers don't compile as C++), -lcombase dropped, a reference leak fixed.

perf(tlas): dirty-track the per-frame TLAS instance+metadata upload (#118)
BuildTLAS rebuilt the host instance+metadata buffers with an O(n) copy of
every 64 B VkAccelerationStructureInstanceKHR + metadata entry every frame,
unconditionally, then flushed the whole high-water capacity (VK_WHOLE_SIZE)
on both buffers. At the millions-of-instances target that copy dominates the
CPU frame, and the whole-buffer flush costs on non-coherent BAR/VRAM.
Add a generation counter so only changed host-authored fields are copied, and
feed the same dirty span into the ranged FlushDevice(offset, bytes) overload:
- RenderingElement3D::hostDataVersion + MarkHostDataDirty() (bumps a global
monotonic counter). TlasWithBuffer::uploadedVersion records, per frame, the
version last copied into each slot. A slot is copied only when its element
advanced past the recorded version; version 0 ("untracked") reads dirty every
frame, so callers that don't opt in keep the prior copy-every-frame behaviour.
Globally-unique versions make this correct under relocation (Remove's
swap-and-pop, and remove+add that nets the same count on the refit path)
without tracking element identity. The reset on every topology change covers
buffer reallocation and the reshuffled element->slot mapping.
- The dirty [first, last] envelope drives both the copy and the flush: a new
VulkanBuffer::FlushDevice(cmd, access, stage, offset, bytes) overload flushes
+ barriers just that span for instanceBuffer, and the ranged
FlushDevice(offset, bytes) for metadataBuffer. When nothing is dirty both are
skipped — the skipped HOST->build barrier only ever ordered host writes, never
the application's compute-written GPU-owned transform (that compute->build
ordering is the caller's, and is unchanged).
Constraint honoured: transformOwnedByGpu transforms are still never host-copied.
The API field/method are mirrored on the WebGPU class for source portability
(the WebGPU build re-uploads its small mirror wholesale and ignores the version).
New test TLASInstanceDirtyTracking drives the real RT device and reads back the
host-mapped buffers to assert: tracked elements upload once then skip until
re-marked, untracked elements always upload, and relocation on the refit path
re-uploads exactly the moved slots — with zero validation-layer errors over the
ranged flush.

fix(font-atlas): give glyphs that find no room a cell when the next frame begins, evicting the least recently drawn
The atlas packed glyphs onto shelves and never gave a place back (#55).
Once its 1024x1024 image was full, EnsureAndGet returned nullptr for each
new glyph before caching anything, so every new string holding one
rasterised it again, and ShapeText dropped it together with its advance:
the rest of the line closed up over the gap, and stayed that way.
FontAtlas
- A glyph is measured, not rasterised, until it gets a cell. One that
finds no free room keeps its advance and box and draws blank for a
frame. EnsureAndGet always returns the glyph, now a reference;
Glyph::Resident() says whether it has a cell, Glyph::handle which one
(slot and generation).
- Evictions wait for the next frame: its first EnsureAndGet, Touch or
Update places the glyphs that waited, once every glyph the frame before
drew has been marked. Evicting while a frame is still asking for glyphs
took ones it drew further down, which then took others in turn: a page
switched back to could rasterise most of itself again rather than what
it was missing, and on the DOM backend an over-full view could do so
every frame.
- A glyph keeps its cell for framesInFlight + 1 frames after it was drawn.
The frame loop waits frame u's fence at the start of frame
u + framesInFlight, but Device::frameCounter reads that from the end of
the frame before, and input callbacks and onBeforeUpdate run in between.
- FontAtlas::Packer places glyphs. Until the rows run out it fills shelves
exactly as before. Then a glyph takes the same columns of one shelf at
least as tall, or of several in a row as tall together, the free rows
below the last shelf counting as one more: free texels, and, when the
frame begins, glyphs nothing in flight draws, the least recently drawn
first. A glyph spanning shelves lets in one taller than every shelf, and
a few glyphs drawn every frame pin only their columns. Merging whole
shelves instead, tried first, left a random workload without room for a
glyph while a median 43% of the atlas was in flight; spanning, at 65%.
- A box that found no room in a frame is remembered, with every box at
least as big, as a small set per mode, until the frame ends or (without
eviction) something is evicted: a saturated atlas no longer searches
every shelf for each of its missing glyphs.
- An evicted glyph is forgotten, and its texels are zeroed and uploaded
with the glyph that takes its place: a neighbour's filtering at its edge
must read padding or zero, not a stale glyph.
- Touch(handles) marks every glyph whose handle still holds its cell, and
says whether all did. InvalidateFont(font) forgets the font's glyphs and
those waiting for a cell, whose Font* the next frame would read. The
glyph index is looked up at rasterisation, so a Font replaced in place
never gets one past its glyphs. GlyphsRasterized() counts, for tests.
UIRenderer
- A shaped run keeps a handle per glyph it draws. A hit touches them all,
so the atlas keeps what is drawn every frame, and shapes the run again
when one was evicted or one had no room. A glyph without room draws
blank but advances the pen.
- InvalidateFont clears the atlas's glyphs of the font too, as its comment
and AGENTS.md always said it did.
- Record calls the atlas's Update before onBuild, every frame, so the
waiting glyphs are placed and uploaded first. Dispatch uploads the atlas
before any kernel, a Tier 1 one sampling FontAtlasImageSlot() included:
a glyph placed earlier in onBuild can sit in a cell another glyph had.
DispatchText and DispatchFused no longer do it themselves.
Device, Window (DOM)
- Device::frameCounter and Device::framesInFlight exist on the DOM backend
too, the counter bumped at the end of Window::Render, with one frame in
flight: a frame's writeTexture lands before that frame's submit but after
every earlier one.
HelloUI
- One set of item buffers and slots per frame in flight, by frameIdx. A
frame still on the GPU read the items the next frame's onBuild was
rewriting; with cells changing hands, those can name cells it drew other
glyphs in.
Tests
- FontAtlasPacker: the packer with made-up boxes and no device: the fill
order, least recently drawn first, framesInFlight + 1 frames held,
nothing without evict, wide glyphs, tall glyphs spanning shelves and the
free rows, Touch past a stale handle, stale handles, dirty spans, and the
invariants over a random workload placed the way the atlas places.
- FontAtlasEviction: fills the atlas through ShapeText frame by frame. The
line that no longer fits keeps its advance and its glyphs' places; its
missing glyphs aren't rasterised while nothing can go; when only line 0
is cold, only its glyphs give way; a frame's own misses evict nothing in
it; a frame later the line and twenty more are whole, pixel for pixel,
line 0 losing a larger share than the glyphs drawn after it; a stale
cached run is shaped again; no stale texel is left; InvalidateFont
reaches the atlas. Against master, with its two calls to the new API
stubbed out, an earlier version failed ten checks.
- UIDispatchAtlasFlush: a custom ui.Dispatch after ShapeText leaves the
atlas uploaded. Needs a compositor.
- ShapeTextCache: a hit rasterises nothing; after InvalidateFont the
re-shaped run draws the same, from new cells.
Docs
- README and AGENTS.consumer.md: the atlas's eviction, the frame a glyph
waits, shaping text every frame into per-frame item buffers,
InvalidateFont, EnsureAndGet's signature and Lookup's lifetime, and that
the atlas, like the deletion queue, assumes one rendering window and
evicts nothing without one.
- AGENTS.md: FontAtlas::Packer among the pure-logic helpers, eviction
without a Window, and InvalidateFont.
Breaking: FontAtlas::EnsureAndGet returns const Glyph& and never fails;
check Glyph::Resident() before drawing from its UVs. FontAtlas::Touch is
no longer noexcept. A GlyphItem is good for the frame it was shaped for,
once the atlas has filled up, and item buffers must be per frame.

perf(text): cache shaped runs in ShapeText (#52)
ShapeText re-decoded UTF-8, re-looked-up every glyph, and recomputed
layout every frame for static strings (DrawText / EmitCenteredLabel run
inside per-frame onBuild). DrawText and EmitCenteredLabel also did a
second full pass over the glyphs to apply alignment.
Memoize the shaped run, keyed by (Font*, pxSize, color, utf8), as an
origin-relative vector<GlyphItem>. A cache hit skips decode/lookup/layout
and just translates the cached run into the output buffer by
(x + alignShift, baselineY). The alignment shift (Center = -advance/2,
Right = -advance) is folded into ShapeText's single pass, dropping the
second loop in both callers. TextAlign moves to the :UI partition so
ShapeText can take it.
Pure CPU memoization — the glyph buffer is fully rewritten and re-flushed
every frame, so a hit is byte-equivalent. A miss still calls Ensure so new
glyphs rasterise and dirty the atlas; hits don't (atlas entries are never
evicted). InvalidateFont drops a font's runs before it is destroyed (the
cache, like FontAtlas's glyph cache, keys on the Font pointer). A soft cap
bounds memory against pathological per-frame-unique text.
Adds the ShapeTextCache test (15 checks): hit == miss byte-for-byte, hits
don't touch the atlas, translate/alignment/truncation/InvalidateFont.

The atlas packed glyphs onto shelves and never gave a place back (#55).
Once its 1024x1024 image was full, EnsureAndGet returned nullptr for each

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles

a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the

The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT

perf(text): cache shaped runs in ShapeText (#52)
ShapeText re-decoded UTF-8, re-looked-up every glyph, and recomputed
layout every frame for static strings (DrawText / EmitCenteredLabel run
inside per-frame onBuild). DrawText and EmitCenteredLabel also did a
second full pass over the glyphs to apply alignment.
Memoize the shaped run, keyed by (Font*, pxSize, color, utf8), as an
origin-relative vector<GlyphItem>. A cache hit skips decode/lookup/layout
and just translates the cached run into the output buffer by
(x + alignShift, baselineY). The alignment shift (Center = -advance/2,
Right = -advance) is folded into ShapeText's single pass, dropping the
second loop in both callers. TextAlign moves to the :UI partition so
ShapeText can take it.
Pure CPU memoization — the glyph buffer is fully rewritten and re-flushed
every frame, so a hit is byte-equivalent. A miss still calls Ensure so new
glyphs rasterise and dirty the atlas; hits don't (atlas entries are never
evicted). InvalidateFont drops a font's runs before it is destroyed (the
cache, like FontAtlas's glyph cache, keys on the Font pointer). A soft cap
bounds memory against pathological per-frame-unique text.
Adds the ShapeTextCache test (15 checks): hit == miss byte-for-byte, hits
don't touch the atlas, translate/alignment/truncation/InvalidateFont.

fix(font-atlas): give glyphs that find no room a cell when the next frame begins, evicting the least recently drawn
The atlas packed glyphs onto shelves and never gave a place back (#55).
Once its 1024x1024 image was full, EnsureAndGet returned nullptr for each
new glyph before caching anything, so every new string holding one
rasterised it again, and ShapeText dropped it together with its advance:
the rest of the line closed up over the gap, and stayed that way.
FontAtlas
- A glyph is measured, not rasterised, until it gets a cell. One that
finds no free room keeps its advance and box and draws blank for a
frame. EnsureAndGet always returns the glyph, now a reference;
Glyph::Resident() says whether it has a cell, Glyph::handle which one
(slot and generation).
- Evictions wait for the next frame: its first EnsureAndGet, Touch or
Update places the glyphs that waited, once every glyph the frame before
drew has been marked. Evicting while a frame is still asking for glyphs
took ones it drew further down, which then took others in turn: a page
switched back to could rasterise most of itself again rather than what
it was missing, and on the DOM backend an over-full view could do so
every frame.
- A glyph keeps its cell for framesInFlight + 1 frames after it was drawn.
The frame loop waits frame u's fence at the start of frame
u + framesInFlight, but Device::frameCounter reads that from the end of
the frame before, and input callbacks and onBeforeUpdate run in between.
- FontAtlas::Packer places glyphs. Until the rows run out it fills shelves
exactly as before. Then a glyph takes the same columns of one shelf at
least as tall, or of several in a row as tall together, the free rows
below the last shelf counting as one more: free texels, and, when the
frame begins, glyphs nothing in flight draws, the least recently drawn
first. A glyph spanning shelves lets in one taller than every shelf, and
a few glyphs drawn every frame pin only their columns. Merging whole
shelves instead, tried first, left a random workload without room for a
glyph while a median 43% of the atlas was in flight; spanning, at 65%.
- A box that found no room in a frame is remembered, with every box at
least as big, as a small set per mode, until the frame ends or (without
eviction) something is evicted: a saturated atlas no longer searches
every shelf for each of its missing glyphs.
- An evicted glyph is forgotten, and its texels are zeroed and uploaded
with the glyph that takes its place: a neighbour's filtering at its edge
must read padding or zero, not a stale glyph.
- Touch(handles) marks every glyph whose handle still holds its cell, and
says whether all did. InvalidateFont(font) forgets the font's glyphs and
those waiting for a cell, whose Font* the next frame would read. The
glyph index is looked up at rasterisation, so a Font replaced in place
never gets one past its glyphs. GlyphsRasterized() counts, for tests.
UIRenderer
- A shaped run keeps a handle per glyph it draws. A hit touches them all,
so the atlas keeps what is drawn every frame, and shapes the run again
when one was evicted or one had no room. A glyph without room draws
blank but advances the pen.
- InvalidateFont clears the atlas's glyphs of the font too, as its comment
and AGENTS.md always said it did.
- Record calls the atlas's Update before onBuild, every frame, so the
waiting glyphs are placed and uploaded first. Dispatch uploads the atlas
before any kernel, a Tier 1 one sampling FontAtlasImageSlot() included:
a glyph placed earlier in onBuild can sit in a cell another glyph had.
DispatchText and DispatchFused no longer do it themselves.
Device, Window (DOM)
- Device::frameCounter and Device::framesInFlight exist on the DOM backend
too, the counter bumped at the end of Window::Render, with one frame in
flight: a frame's writeTexture lands before that frame's submit but after
every earlier one.
HelloUI
- One set of item buffers and slots per frame in flight, by frameIdx. A
frame still on the GPU read the items the next frame's onBuild was
rewriting; with cells changing hands, those can name cells it drew other
glyphs in.
Tests
- FontAtlasPacker: the packer with made-up boxes and no device: the fill
order, least recently drawn first, framesInFlight + 1 frames held,
nothing without evict, wide glyphs, tall glyphs spanning shelves and the
free rows, Touch past a stale handle, stale handles, dirty spans, and the
invariants over a random workload placed the way the atlas places.
- FontAtlasEviction: fills the atlas through ShapeText frame by frame. The
line that no longer fits keeps its advance and its glyphs' places; its
missing glyphs aren't rasterised while nothing can go; when only line 0
is cold, only its glyphs give way; a frame's own misses evict nothing in
it; a frame later the line and twenty more are whole, pixel for pixel,
line 0 losing a larger share than the glyphs drawn after it; a stale
cached run is shaped again; no stale texel is left; InvalidateFont
reaches the atlas. Against master, with its two calls to the new API
stubbed out, an earlier version failed ten checks.
- UIDispatchAtlasFlush: a custom ui.Dispatch after ShapeText leaves the
atlas uploaded. Needs a compositor.
- ShapeTextCache: a hit rasterises nothing; after InvalidateFont the
re-shaped run draws the same, from new cells.
Docs
- README and AGENTS.consumer.md: the atlas's eviction, the frame a glyph
waits, shaping text every frame into per-frame item buffers,
InvalidateFont, EnsureAndGet's signature and Lookup's lifetime, and that
the atlas, like the deletion queue, assumes one rendering window and
evicts nothing without one.
- AGENTS.md: FontAtlas::Packer among the pure-logic helpers, eviction
without a Window, and InvalidateFont.
Breaking: FontAtlas::EnsureAndGet returns const Glyph& and never fails;
check Glyph::Resident() before drawing from its UVs. FontAtlas::Touch is
no longer noexcept. A GlyphItem is good for the frame it was shaped for,
once the atlas has filled up, and item buffers must be per frame.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be

- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT
headers don't compile as C++), -lcombase dropped, a reference leak fixed.
- project.cpp honours --local for Crafter.Event, Math and Asset, as Asset
does for Math, and builds every test through one helper, projectArgs
included.
- Tests: DebugMessengerSeverity, DeletionQueueThreads, DeviceSelection,
HeapSlotReuse, MeshLifetime, MipChainNonSquare, PipelineLifetime,
RTPassPushData, SwapchainTransferDst, UploadInFlight, VulkanBufferAddress,
VulkanShaderLifetime, WindowUpdateClock; others extended.
Breaking: SaveFrame is CaptureNextFrame; Mesh::opaque is geometryFlags; a
buffer without SHADER_DEVICE_ADDRESS usage has no address; frameCounter is
std::atomic.

fix(rt): split Sponza's combined image sampler into a heap texture and sampler
examples/Sponza no longer built natively (#164). Its closest-hit declared a
descriptor_heap sampler2D, which glslang has rejected since c8253623
("Reject descriptor_heap combined image samplers"), and main.cpp wrote it
through VkResourceDescriptorDataEXT::pCombinedImageSampler, which that union
no longer has: the descriptor heap has no combined image samplers. Both went
unnoticed because nothing builds the examples.
Sponza
- closesthit.glsl declares texture2D and sampler heap arrays and joins them
where it samples, as ui-shared.glsl and HeapDynamicIndexHit do. The
sampler slot is a second spec constant beside the image slot, so the
shader assumes nothing about where the host put it, and a constant index
keeps the example running on NVIDIA 610.43.02 (see its README). The
comment no longer says the image slot is offset by bufferStartElement;
only buffer slots are.
- main.cpp gives the heap a sampler slot, writes the albedo as a
SAMPLED_IMAGE from a view create-info, and writes the sampler into the
sampler heap from a VkSamplerCreateInfo with vkWriteSamplerDescriptorsEXT,
as UIRenderer::RegisterSampler does. SamplerVulkan's VkSampler had no use
left. The sampler keeps its linear filtering and repeat addressing and
drops anisotropy, which a hit shader cannot use: it samples at LOD 0,
without derivatives.
Docs
- README.md and examples/Sponza/README.md quote the new declarations, and
the Sponza README says why the texture and the sampler are two
descriptors. Its texture2DArray materials pattern declared a
descriptor_heap sampler2DArray, which glslang rejects as well; it now
joins a texture2DArray and a sampler.
- examples/SponzaBench/README.md drops its caveat that Sponza does not
compile.
Tests
- ExampleShaders compiles every GLSL shader under examples/ with glslang as
crafter-build does for the example (Vulkan rules, SPIR-V 1.4, shaders/ on
the include path, and the descriptor-set build where the example
registers one), so a glslang that starts rejecting one fails a test
rather than an example build nobody runs. It fails on Sponza's old
closest-hit and needs glslang only.
Closes #164.

fix(ui): decode the font atlas's SDF in atlas pixels, so text edges ramp over one screen pixel
Shaders
- ui-text and ui-fused turned a sample of the R8_UNORM atlas into a
distance with (128/255 - sdf) * 32. stb_truetype writes kOnEdgeValue +
kPixelDistScale * distance into each byte, so an atlas pixel is
kPixelDistScale / 255 of a sample; 32 made every distance 1024/255
(about 4) times too large, and the coverage ramp, meant to span one
screen pixel, spanned a quarter of one: nearly every edge pixel came out
fully on or fully off, and text looked pixelated at every size. On an
RTX 4090, UIFallbackParity's 22 px label had 98 partly covered pixels
where stb_truetype's own rasterizer has 415. Wrong since the v3 UI
(1f56973), and copied into the fused kernel (574242d).
- The decode now lives once, in ui-shared.glsl: UI_SDF_ON_EDGE and
UI_SDF_PIXEL_DIST_SCALE are FontAtlas's two constants in the encoder's
own units, uiSdfDistance decodes a sample, uiGlyphRamp works out a
glyph's ramp when it is loaded and uiGlyphCoverage the coverage per
pixel. Both kernels call them, and a copy of either should; the UI_
prefix keeps them clear of a copied kernel's own names.
- stb_truetype truncates, so a byte b stands for [b, b + 1) of the encoded
value and the decode takes its middle: decoding b pulled every outline
1/64 atlas pixel inwards.
- The ramp is capped at what a byte holds, about 4 atlas pixels each way
of the outline. With the corrected decode a wider one left every glyph
quad's padding translucent below 4 px.
- The UV span is taken with abs(): a glyph turned by swapping its UVs got
a negative scale, a ramp of 0.0001 and hard edges.
- A glyph scaled differently along x and y ramps along the distance's
gradient, from two one-texel differences. With the corrected decode, one
width for both axes, the more minified one's, would leave a row stretched
three times with stems three pixels soft. Glyphs scaled alike, as
ShapeText's are, keep one multiply-add per pixel, the ramp's reciprocal
worked out with the glyph.
- The atlas size is queried rather than FontAtlas::kAtlasSize hard-coded
as 1024.
WebGPU
- The WGSL text kernel decoded the distance right but ramped over one
atlas pixel whatever the size: half a screen pixel at 16 px, two at
64 px. It now repeats ui-shared.glsl's decode, cap, abs and gradient
path, and renders TextAntialiasing's scene as Vulkan does (run through
Deno's WebGPU: 1.02, 1.07 and 1.09 times the reference's edge pixels,
where the old kernel gave 0.55, 2.19 and 0.89).
FontAtlas
- kOnEdgeValue and kPixelDistScale say the kernels carry copies of them.
Tests
- TextAntialiasing draws one string at 14 px, 64 px and 14 px stretched
three times, a 'g' turned by its UVs and empty atlas texels shrunk to
12.8 atlas pixels per screen pixel, through DispatchText and again
through DispatchFused, and holds them to stb_truetype's antialiased
rasterizer, to the mirror image and to nothing. On master the two plain
rows have 0.31 and 0.21 times the reference's edge pixels; with the
decode fixed alone the stretched row had 1.62 times, the turned 'g' was
127 codes off its mirror and the empty texels drew 48. Now: 1.02, 1.07
and 1.09 times, 0 and 0, on the 4090, on llvmpipe and on descriptor
sets. It skips a swapchain that isn't 8-bit, which the capture can't
read, and captures the first frame.
- FontAtlasDecode reads ui-shared.glsl and dom-webgpu.js and holds their
copies of the two constants to FontAtlas's. No GPU.
Docs
- AGENTS.consumer.md has a custom text shader decode through the helpers
and gives the encoding; README says so in a line; AGENTS.md lists the
tests and where the decode lives.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window

is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.

fix(device): fence-keyed deferred resource-deletion queue (#101)
Since #40 dropped the per-frame vkQueueWaitIdle, frames are pipelined:
a resource the CPU is done with may still be read by the GPU for up to
numFrames-1 more frames. VulkanBuffer::Resize's destroy-and-recreate
path was therefore a live use-after-free (#63), no longer masked by the
wait-idle.
Device gains a monotonic, frame-counter-keyed deletion queue:
EnqueueDeletion tags {buffer, memory} with the current frameCounter;

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT
headers don't compile as C++), -lcombase dropped, a reference leak fixed.

fix(device): fence-keyed deferred resource-deletion queue (#101)
Since #40 dropped the per-frame vkQueueWaitIdle, frames are pipelined:
a resource the CPU is done with may still be read by the GPU for up to
numFrames-1 more frames. VulkanBuffer::Resize's destroy-and-recreate
path was therefore a live use-after-free (#63), no longer masked by the
wait-idle.
Device gains a monotonic, frame-counter-keyed deletion queue:
EnqueueDeletion tags {buffer, memory} with the current frameCounter;
ReclaimDeletions (called per frame after the fence wait) frees entries
once framesInFlight frames have elapsed; DrainDeletions frees everything
after a wait-idle. VulkanBuffer::DeferredClear hands handles to the queue
and nulls the handle, and Resize uses it instead of immediate Clear().
Window::Render sets framesInFlight at init, reclaims after the per-image
fence wait, bumps Device::frameCounter once per frame, and drains on the
resize / OUT_OF_DATE wait-idle paths. The destructor keeps immediate
Clear() (callers destroying mid-flight remain responsible, unchanged).
Adds the DeferredDeletion test: drives the retire timing on a real
headless device with real buffers, stepping Device::frameCounter to pin
the exact reclaim frame, asserting validation stays silent.

fix(descriptor-heap): round the buffer region up, align the reserved range for buffers too, and never size a heap at zero
DescriptorHeapVulkan
- The buffer region started at images * imageDescriptorSize /
bufferDescriptorSize, rounded down. A descriptor_heap array indexes
the heap from byte 0 in strides of its descriptor size, so buffer slot
0 has to sit on a whole buffer descriptor past the images. Where the
image descriptors were not a whole number of buffer descriptors, the
first buffer descriptors overwrote the last image descriptors. Where
they were less than one, the start was bumped to descriptor 1, but the
heap was still sized as if the buffers began right after the images,
so the last buffer descriptors went into the implementation's reserved
range. Every descriptor size is a power of two, so both cases need
image descriptors smaller than buffer descriptors, which NVIDIA (32
and 16 bytes) and llvmpipe (64 and 16) do not have. The start now
rounds up and the heap is sized from it (#163).
- The reserved range sat at a multiple of imageDescriptorAlignment only,
where vkCmdBindResourceHeapEXT also wants bufferDescriptorAlignment
(VUID-vkCmdBindResourceHeapEXT-pBindInfo-11435 and -11436). It now
starts on a multiple of the larger. The buffer descriptors need no more
than the rounding: each alignment is at most its descriptor size, so a
whole number of descriptors is aligned.
- bufferStartElement is 16 bits and took the division unchecked, so an
image region past 65535 buffer descriptors (16384 images on llvmpipe)
wrapped the buffer region around onto the images. Slot counts whose
buffer indices do not fit 16 bits, 0xFFFF being the empty slot, now
throw, naming the counts. A heap without buffer slots has no buffer
region, which starts at 0 as in descriptor-set mode, so image-only
heaps have no index to fit.
- On a driver that reserves nothing (llvmpipe), a heap without sampler
slots was a zero-size buffer, which every Initialize(1, 1, 0) made,
and Window::Render bound its address each frame. Each heap now holds at
least one descriptor, as each binding does in descriptor-set mode. That
grows NVIDIA's sampler heap by one descriptor when no sampler slots are
asked for; the resource heaps of the slot counts in the tree keep their
layouts byte for byte.
- ComputeLayout holds the arithmetic, pure over the descriptor-heap
properties, and Initialize goes through it. GetBufferOffset and
GetBufferOffsetElement, which had their own copies of the old
arithmetic and never had a caller, are gone.
- Bind(cmd, frame) binds a frame's heaps with the reserved ranges
Initialize stored, or in descriptor-set mode the frame's descriptor
set. Window::Render and the RTVolume example worked the reserved-range
offset out from the heap's size with the image-alignment mask, and
call Bind now. The window's per-heap cache of bind structs goes with
it: keyed on the heap pointer, it kept binding the old buffers after a
re-Initialize that reallocated them. The heap still ends with its
reserved range, so code that derives the offset from the size keeps
getting the right one.
Tests
- DescriptorHeapLayout: the issue's two layouts, the reserved range where
buffer descriptors are aligned more strictly than image ones, every
legal combination of descriptor sizes and alignments up to 256 bytes,
no heap empty, the NVIDIA and llvmpipe layouts, the 16-bit limit and
image-only heaps. Pure CPU, no device. Against the old arithmetic it
fails 12 of its 18 checks.
Docs
- README.md's heap bullet and AGENTS.consumer.md say how to bind the
heap outside the frame loop, and the consumer notes that Initialize
throws when buffer indices would pass 16 bits. AGENTS.md lists
ComputeLayout among the functions the pure-logic tests drive.
Closes #163.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window

compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT
headers don't compile as C++), -lcombase dropped, a reference leak fixed.
- project.cpp honours --local for Crafter.Event, Math and Asset, as Asset
does for Math, and builds every test through one helper, projectArgs
included.
- Tests: DebugMessengerSeverity, DeletionQueueThreads, DeviceSelection,
HeapSlotReuse, MeshLifetime, MipChainNonSquare, PipelineLifetime,
RTPassPushData, SwapchainTransferDst, UploadInFlight, VulkanBufferAddress,
VulkanShaderLifetime, WindowUpdateClock; others extended.
Breaking: SaveFrame is CaptureNextFrame; Mesh::opaque is geometryFlags; a
buffer without SHADER_DEVICE_ADDRESS usage has no address; frameCounter is
std::atomic.

their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.
- Windows: the WinRT gamepad code moved to a C file (mingw-w64's WinRT
headers don't compile as C++), -lcombase dropped, a reference leak fixed.
- project.cpp honours --local for Crafter.Event, Math and Asset, as Asset
does for Math, and builds every test through one helper, projectArgs
included.
- Tests: DebugMessengerSeverity, DeletionQueueThreads, DeviceSelection,
HeapSlotReuse, MeshLifetime, MipChainNonSquare, PipelineLifetime,
RTPassPushData, SwapchainTransferDst, UploadInFlight, VulkanBufferAddress,
VulkanShaderLifetime, WindowUpdateClock; others extended.
Breaking: SaveFrame is CaptureNextFrame; Mesh::opaque is geometryFlags; a
buffer without SHADER_DEVICE_ADDRESS usage has no address; frameCounter is
std::atomic.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window

compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both

whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.

in place or erased from a vector.

feat: windows on their own clock, deferred deletion for every handle owner, staged re-uploads, and RTPass push data
Window
- updateInterval runs Update on the window's own clock while the
compositor sends no frame callbacks (hidden, minimized): the Wayland loop
is a poll() loop, and the Win32 loop sleeps until the next update. Both
read the interval each pass.
- SetPresentMode (FIFO, Mailbox, Immediate). A mode the surface lacks, or
whose swapchain has other than numFrames images (Mesa's Mailbox has four),
falls back to FIFO until the mode is set again.
- AddPollFd / RemovePollFd wake the Wayland loop on the app's descriptors.
- The swapchain has TRANSFER_DST where the surface allows it.
- CaptureNextFrame replaces SaveFrame: it records the copy in the frame,
before the present, where SaveFrame read an image already presented. A
frame unwound past before the write still frees the readback buffer.
- Inter-pass barriers on the swapchain image carry the access masks of the
stages the passes use.
Deferred deletion (issue #101)
- VulkanBuffer, Mesh, VulkanShader, ComputeShader and PipelineRTVulkan hand
their handles to the deletion queue from their destructors and moves, as
a frame in flight may still use them; a static owner goes after the
driver has torn down. VulkanShader and PipelineRTVulkan move and can't be
copied; re-Load and re-Init queue the old pipeline.
- The queue and its mutex are never destroyed, and the queue takes handles
from any thread; Device::frameCounter is atomic. Both the queue and the
staging rings count frames as one window renders them (documented).
- DrainDeletions also lets every buffer's staging ring start over: without
a Window nothing else reclaims either, so an app without one calls it
after waiting for its work.
Meshes and buffers
- A Mesh rebuild queues the old acceleration structure and builds into the
same storage after a barrier, so the BLAS address stays put when it fits.
The refit and rebuild barriers cover compute ray queries too.
- RTBuildOptions::noDuplicateAnyHit. Mesh::geometryFlags replaces opaque,
and the refit and rebuild fallbacks keep the flags.
- A re-upload into a buffer a frame in flight may read (UploadDeviceLocal
of the same size, UploadDeviceLocalRange) copies on the GPU, after those
reads, through a per-frame staging ring; on ReBAR it used to write the
buffer in place. Empty uploads record nothing.
- A compressed Mesh::Build that keeps its buffers decompresses into them
after the reads of frames in flight, and the hit shaders and ray queries
wait for the decompress as well as the BLAS build. Its vertex buffer
takes a ranged refit's copies.
- Mesh move-assigns (queueing the BLAS it replaces), so it can be replaced
in place or erased from a vector.
- VulkanBuffer::Create asks for a device address only for buffers with
SHADER_DEVICE_ADDRESS usage, as vkGetBufferDeviceAddress requires; the
others have address 0. UIRenderer::RegisterBuffer refuses those.
- Build inputs are synchronized as shader reads.
Other
- RTPass pushes the app's own push data and traces at an explicit size.
- DescriptorHeapVulkan hands freed slot ranges out again (they leaked), and
keeps its free lists sorted.
- ImageVulkan's mip chain clamps each level to 1 texel: a non-square
image's shorter side went to 0.
- VulkanShader throws on a missing file instead of failing in bad_alloc.
- CRAFTER_GRAPHICS_DEVICE picks the GPU by its number among the distinct
GPUs Vulkan lists; anything but such a number is an error.
- The debug messenger prints info messages only with
CRAFTER_GRAPHICS_VALIDATION set.

headers don't compile as C++), -lcombase dropped, a reference leak fixed.

does for Math, and builds every test through one helper, projectArgs
included.

HeapSlotReuse, MeshLifetime, MipChainNonSquare, PipelineLifetime,
RTPassPushData, SwapchainTransferDst, UploadInFlight, VulkanBufferAddress,
VulkanShaderLifetime, WindowUpdateClock; others extended.

feat(device): applications ask for the device features their shaders use
Device
- Device::Initialize(required, optional) takes DeviceFeatures, the five
core feature structs vulkan10 to vulkan14. The library enables only what
its own shaders and code use. Device::enabledFeatures says what was
enabled, supportedFeatures what the GPU has, apiVersion the version in
use.
- shaderInt16, shaderFloat16, storageBuffer16BitAccess, scalarBlockLayout
and the uniform-buffer, storage-buffer and storage-image non-uniform
indexing bits are no longer enabled for everyone. An application whose
shaders take uint16_t spec constants passes
{.vulkan10 = {.shaderInt16 = VK_TRUE}}. scalarBlockLayout stays on with
the NVIDIA workaround, whose TLAS address may sit in a struct's tail
padding.
- Every GPU is weighed before one is chosen: Vulkan 1.3, the swapchain and,
below 1.4, maintenance5 extensions, the library's needs, the required
features. One that can't run the application is skipped, saying why when
it ranks higher. A CPU device runs it only when nothing else is listed,
and CRAFTER_GRAPHICS_DEVICE never falls back. A GPU two drivers both list
is tried through each.
- When no GPU qualifies, Initialize throws naming each GPU's gaps. It
destroys the instance it made, before any Wayland connection, so it can
be called again asking for less.
- maintenance5 is vulkan14's on a 1.4 GPU and VK_KHR_maintenance5's below.
CRAFTER_GRAPHICS_NO_VULKAN_1_4 runs as a 1.3 application, to exercise
that path on a 1.4 GPU.
- VK_KHR_spirv_1_4 and VK_KHR_shader_float_controls, core since 1.2, are no
longer enabled, nor VK_EXT_shader_atomic_float, which was enabled without
its feature struct. memoryDecompression's feature bit is queried before
it is enabled.
Shaders
- VulkanShader checks a module's capabilities, declared directly or
implicitly, against the enabled core features, the GPU's subgroup
operations and the optional groups, and throws naming the field to pass,
or saying the GPU lacks it. The tables are generated from vk.xml and
SPIR-V's grammar.
- WorkaroundNvidiaAS::Patch sized a row-major matrix push member by its
columns, so the TLAS address could land inside it.
Window
- The swapchain format is one whose own feature flags allow storage reads
and writes without a format, which since Vulkan 1.3 each format says for
itself; shaderStorageImageRead/WriteWithoutFormat are no longer required.
Tests
- DeviceFeatures: ResolveFeatures, ChooseDevice and CheckShaderCapabilities,
without a GPU.
- FeatureRequests: required and optional features end to end, the 1.3
path, and a retry after a refusal.
- PushConstantRewrite: a row-major mat3x4 push member.
- HeapASRead, HeapDynamicIndexHit, RTPassPushData and the ray-tracing
examples ask for the features their shaders use.
