VkPhysicalDeviceRayTracingPipelinePropertiesKHR

The VkPhysicalDeviceRayTracingPipelinePropertiesKHR structure is defined as:

typedef struct VkPhysicalDeviceRayTracingPipelinePropertiesKHR {
    VkStructureType sType;
    void* pNext;
    uint32_t shaderGroupHandleSize;
    uint32_t maxRayRecursionDepth;
    uint32_t maxShaderGroupStride;
    uint32_t shaderGroupBaseAlignment;
    uint32_t shaderGroupHandleCaptureReplaySize;
    uint32_t maxRayDispatchInvocationCount;
    uint32_t shaderGroupHandleAlignment;
    uint32_t maxRayHitAttributeSize;
} VkPhysicalDeviceRayTracingPipelinePropertiesKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• shaderGroupHandleSize is the size in bytes of the shader header.
• maxRayRecursionDepth is the maximum number of levels of ray recursion allowed in a trace command.
• maxShaderGroupStride is the maximum stride in bytes allowed between shader groups in the shader binding table.
• shaderGroupBaseAlignment is the required alignment in bytes for the base of the shader binding table.
• shaderGroupHandleCaptureReplaySize is the number of bytes for the information required to do capture and replay for shader group handles.
• maxRayDispatchInvocationCount is the maximum number of ray generation shader invocations which may be produced by a single vkCmdTraceRaysIndirectKHR or vkCmdTraceRaysKHR command.
• shaderGroupHandleAlignment is the required alignment in bytes for each entry in a shader binding table. The value must be a power of two.
• maxRayHitAttributeSize is the maximum size in bytes for a ray attribute structure

If the VkPhysicalDeviceRayTracingPipelinePropertiesKHR structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Limits specified by this structure must match those specified with the same name in VkPhysicalDeviceRayTracingPropertiesNV.
