C Specification
The VkPhysicalDeviceRayTracingFeaturesKHR structure is defined as:
typedef struct VkPhysicalDeviceRayTracingFeaturesKHR {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           rayTracing;
    VkBool32           rayTracingShaderGroupHandleCaptureReplay;
    VkBool32           rayTracingShaderGroupHandleCaptureReplayMixed;
    VkBool32           rayTracingAccelerationStructureCaptureReplay;
    VkBool32           rayTracingIndirectTraceRays;
    VkBool32           rayTracingIndirectAccelerationStructureBuild;
    VkBool32           rayTracingHostAccelerationStructureCommands;
    VkBool32           rayQuery;
    VkBool32           rayTracingPrimitiveCulling;
} VkPhysicalDeviceRayTracingFeaturesKHR;Members
The members of the VkPhysicalDeviceRayTracingFeaturesKHR structure
describe the following features:
Description
- 
rayTracingindicates whether the implementation supports ray tracing functionality. See Ray Tracing.
- 
rayTracingShaderGroupHandleCaptureReplayindicates whether the implementation supports saving and reusing shader group handles, e.g. for trace capture and replay.
- 
rayTracingShaderGroupHandleCaptureReplayMixedindicates whether the implementation supports reuse of shader group handles being arbitrarily mixed with creation of non-reused shader group handles. If this isVK_FALSE, all reused shader group handles must be specified before any non-reused handles may be created.
- 
rayTracingAccelerationStructureCaptureReplayindicates whether the implementation supports saving and reusing acceleration structure device addresses, e.g. for trace capture and replay.
- 
rayTracingIndirectTraceRaysindicates whether the implementation supports indirect trace ray commands, e.g. vkCmdTraceRaysIndirectKHR.
- 
rayTracingIndirectAccelerationStructureBuildindicates whether the implementation supports indirect acceleration structure build commands, e.g. vkCmdBuildAccelerationStructureIndirectKHR.
- 
rayTracingHostAccelerationStructureCommandsindicates whether the implementation supports host side acceleration structure commands, e.g. vkBuildAccelerationStructureKHR, vkCopyAccelerationStructureKHR, vkCopyAccelerationStructureToMemoryKHR, vkCopyMemoryToAccelerationStructureKHR, vkWriteAccelerationStructuresPropertiesKHR.
- 
rayQueryindicates whether the implementation supports ray query (OpRayQueryProceedKHR) functionality.
- 
rayTracingPrimitiveCullingindicates whether the implementation supports primitive culling during ray traversal.
If the VkPhysicalDeviceRayTracingFeaturesKHR structure is included in
the pNext chain of VkPhysicalDeviceFeatures2, it is filled with
values indicating whether the feature is supported.
VkPhysicalDeviceRayTracingFeaturesKHR can also be used in the
pNext chain of VkDeviceCreateInfo to enable the features.
