# HelloWindow Example
## Description
This example showcases how to use the camera to get a rotating 3D cube.
## Expected Result
A blue tinted vulkan window with a white rotating 3D cube.
## Highlighted Code Snippet
```cpp
Camera camera(ToRadian(90), 1280.0f / 720.0f, 0.01, 512);
camera.view = MatrixRowMajor<float, 4, 4, 1>::Translation(0, 0, -5);
camera.Update();
```
## How to Run
```bash
crafter-build build executable -r
```

This example showcases how to define a custom shader.
## Expected Result
A RGB triangle.
## Highlighted Code Snippet
```cpp

memcpy(this->colors.value, colors.data(), colors.size()*sizeof(Vector<float, 4>));
}
void WriteDescriptors(VkDescriptorSet set) {
