Description

This example showcases how to define a custom shader.

Expected Result

A RGB triangle.

Highlighted Code Snippet

class CustomShader {
    public:
    Buffer<Vector<float, 4>> colors;
    CustomShader(const std::vector<Vector<float, 4>>& colors) : colors(VK_BUFFER_USAGE_STORAGE_BUFFER_BIT, VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT | VK_MEMORY_PROPERTY_HOST_COHERENT_BIT, colors.size()) {
        memcpy(this->colors.value, colors.data(), colors.size()*sizeof(Vector<float, 4>));
    }
    void WriteDescriptors(VkDescriptorSet set) {
        VkWriteDescriptorSet write[1] = {
            vks::initializers::writeDescriptorSet(set, VK_DESCRIPTOR_TYPE_STORAGE_BUFFER, 0, &colors.descriptor),
        };
        vkUpdateDescriptorSets(VulkanDevice::device, 1, &write[0], 0, nullptr);
    }
};
