C Specification
The VkPhysicalDeviceRayTracingFeaturesKHR
structure is defined as:
// Provided by VK_KHR_ray_tracing
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
-
rayTracing
indicates whether the implementation supports ray tracing functionality. See Ray Tracing. -
rayTracingShaderGroupHandleCaptureReplay
indicates whether the implementation supports saving and reusing shader group handles, e.g. for trace capture and replay. -
rayTracingShaderGroupHandleCaptureReplayMixed
indicates 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. -
rayTracingAccelerationStructureCaptureReplay
indicates whether the implementation supports saving and reusing acceleration structure device addresses, e.g. for trace capture and replay. -
rayTracingIndirectTraceRays
indicates whether the implementation supports indirect trace ray commands, e.g. vkCmdTraceRaysIndirectKHR. -
rayTracingIndirectAccelerationStructureBuild
indicates whether the implementation supports indirect acceleration structure build commands, e.g. vkCmdBuildAccelerationStructureIndirectKHR. -
rayTracingHostAccelerationStructureCommands
indicates whether the implementation supports host side acceleration structure commands, e.g. vkBuildAccelerationStructureKHR, vkCopyAccelerationStructureKHR, vkCopyAccelerationStructureToMemoryKHR, vkCopyMemoryToAccelerationStructureKHR, vkWriteAccelerationStructuresPropertiesKHR. -
rayQuery
indicates whether the implementation supports ray query (OpRayQueryProceedKHR
) functionality. -
rayTracingPrimitiveCulling
indicates 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.
