Description
This extension introduces new commands to put shader-accessible descriptors directly in memory, making the management of descriptor data more explicit.
New Commands
- vkCmdBindDescriptorBufferEmbeddedSamplersEXT
- vkCmdBindDescriptorBuffersEXT
- vkCmdSetDescriptorBufferOffsetsEXT
- vkGetBufferOpaqueCaptureDescriptorDataEXT
- vkGetDescriptorEXT
- vkGetDescriptorSetLayoutBindingOffsetEXT
- vkGetDescriptorSetLayoutSizeEXT
- vkGetImageOpaqueCaptureDescriptorDataEXT
- vkGetImageViewOpaqueCaptureDescriptorDataEXT
- vkGetSamplerOpaqueCaptureDescriptorDataEXT
If VK_KHR_acceleration_structure or VK_NV_ray_tracing is supported:
New Structures
- VkBufferCaptureDescriptorDataInfoEXT
- VkDescriptorAddressInfoEXT
- VkDescriptorBufferBindingInfoEXT
- VkDescriptorGetInfoEXT
- VkImageCaptureDescriptorDataInfoEXT
- VkImageViewCaptureDescriptorDataInfoEXT
