C Specification

The VkPhysicalDeviceRayTracingPipelineFeaturesKHR structure is defined as:

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

Members

This structure describes the following features:

Description

  • 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. VkPhysicalDeviceRayTracingPipelineFeaturesKHR can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage

  • VUID-VkPhysicalDeviceRayTracingPipelineFeaturesKHR-rayTracingPipelineShaderGroupHandleCaptureReplayMixed-03575
    If rayTracingPipelineShaderGroupHandleCaptureReplayMixed is VK_TRUE, rayTracingPipelineShaderGroupHandleCaptureReplay must also be VK_TRUE

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceRayTracingPipelineFeaturesKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_RAY_TRACING_PIPELINE_FEATURES_KHR
