voidcreateDescriptorSetLayout(){VkDescriptorSetLayoutBindinguboLayoutBinding{};uboLayoutBinding.binding=0;uboLayoutBinding.descriptorType=VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER;uboLayoutBinding.descriptorCount=1;} 每个Binding都需要通过 VkDescriptorSetLayoutBinding 结构体来描述。前两个字段指定了shader中使用的绑定和Desc...
Vulkan以描述符集(descriptor set)的形式组织描述符,一个descriptor set包含一组descriptor。 示例仅用一个descriptor set的一个descriptor来描述uniform buffer的MVP全局变量。 1.创建Descriptor Set Layout Descriptor set layout用于描述descriptor set: VkDescriptorSetLayoutBinding layout_binding = {}; layout_binding....
...voidcreateDescriptorSetLayout() { } 每个绑定都会通过VkDescriptorSetLayoutBinding结构体描述。 voidcreateDescriptorSetLayout() { VkDescriptorSetLayoutBinding uboLayoutBinding={}; uboLayoutBinding.binding=0; uboLayoutBinding.descriptorType=VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER; uboLayoutBinding.descriptorCount=1;...
Thedescriptor layoutspecifies the types of resources that are going to be accessed by the pipeline, just like a render pass specifies the types of attachments that will be accessed. Adescriptor setspecifies the actual buffer or image resources that will be bound to the descriptors, just like a ...

The advantage of this is model is that we only need to prime descriptor sets for uniform data once: we can then make each buffer binding, within a descriptor set, point to different memory locations in our buffer at bind time, without having to update the offset with costly vkUpdateDescrip...
Combines multiple techniques to render a complex scene consisting of multiple meshes, textures and materials. Meshes are stored and rendered from a single buffer using vertex offsets. Material parameters are passed via push constants, and separate per-model and scene descriptor sets are used to pass...
5. BonesMatrix array (special uniform buffer for matrix pallets)Doing this allows for a clean uniform memory management with as close to zero unnecessary updates as possible.Here's an example of how a base shader looks like in our engine (CausticRays): The...
We first need to describe which descriptor types our descriptor sets are going to contain and how many of them, using VkDescriptorPoolSize structures.VkDescriptorPoolSize poolSize{}; poolSize.type = VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER; poolSize.descriptorCount = static_cast<uint32_t>(MAX_FRAMES_...
Memory type: When creating a resource such as a buffer, Vulkan will provide information about which memory types are compatible with the resource. Depending on additional usage flags, the developer must pick the right type, and based on the type, the appropriate heap. ...
