VkPhysicalDeviceRayTracingPipelineFeaturesKHR

The VkPhysicalDeviceRayTracingPipelineFeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceRayTracingPipelineFeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 rayTracingPipeline;
    VkBool32 rayTracingPipelineShaderGroupHandleCaptureReplay;
    VkBool32 rayTracingPipelineShaderGroupHandleCaptureReplayMixed;
    VkBool32 rayTracingPipelineTraceRaysIndirect;
    VkBool32 rayTraversalPrimitiveCulling;
} VkPhysicalDeviceRayTracingPipelineFeaturesKHR;

This structure describes the following features:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• rayTracingPipeline indicates whether the implementation supports the ray tracing pipeline functionality. See Ray Tracing.
• rayTracingPipelineShaderGroupHandleCaptureReplay indicates whether the implementation supports saving and reusing shader group handles, e.g. for trace capture and replay.
• rayTracingPipelineShaderGroupHandleCaptureReplayMixed indicates whether the implementation supports reuse of shader group handles being arbitrarily mixed with creation of non-reused shader group handles. If this is VK_FALSE, all reused shader group handles must be specified before any non-reused handles may be created.
• rayTracingPipelineTraceRaysIndirect indicates whether the implementation supports indirect ray tracing commands, e.g. vkCmdTraceRaysIndirectKHR.
• rayTraversalPrimitiveCulling indicates whether the implementation supports primitive culling during ray traversal.

If the VkPhysicalDeviceRayTracingPipelineFeaturesKHR structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceRayTracingPipelineFeaturesKHR, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
