VkRayTracingShaderGroupCreateInfoKHR

The VkRayTracingShaderGroupCreateInfoKHR structure is defined as:

typedef struct VkRayTracingShaderGroupCreateInfoKHR {
    VkStructureType sType;
    const void* pNext;
    VkRayTracingShaderGroupTypeKHR type;
    uint32_t generalShader;
    uint32_t closestHitShader;
    uint32_t anyHitShader;
    uint32_t intersectionShader;
    const void* pShaderGroupCaptureReplayHandle;
} VkRayTracingShaderGroupCreateInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• type is the type of hit group specified in this structure.
• generalShader is the index of the ray generation, miss, or callable shader from VkRayTracingPipelineCreateInfoKHR::pStages in the group if the shader group has type of VK_RAY_TRACING_SHADER_GROUP_TYPE_GENERAL_KHR, and VK_SHADER_UNUSED_KHR otherwise.
• closestHitShader is the optional index of the closest hit shader from VkRayTracingPipelineCreateInfoKHR::pStages in the group if the shader group has type of VK_RAY_TRACING_SHADER_GROUP_TYPE_TRIANGLES_HIT_GROUP_KHR or VK_RAY_TRACING_SHADER_GROUP_TYPE_PROCEDURAL_HIT_GROUP_KHR, and VK_SHADER_UNUSED_KHR otherwise.
• anyHitShader is the optional index of the any-hit shader from VkRayTracingPipelineCreateInfoKHR::pStages in the group if the shader group has type of VK_RAY_TRACING_SHADER_GROUP_TYPE_TRIANGLES_HIT_GROUP_KHR or VK_RAY_TRACING_SHADER_GROUP_TYPE_PROCEDURAL_HIT_GROUP_KHR, and VK_SHADER_UNUSED_KHR otherwise.
• intersectionShader is the index of the intersection shader from VkRayTracingPipelineCreateInfoKHR::pStages in the group if the shader group has type of VK_RAY_TRACING_SHADER_GROUP_TYPE_PROCEDURAL_HIT_GROUP_KHR, and VK_SHADER_UNUSED_KHR otherwise.
• pShaderGroupCaptureReplayHandle is NULL or a pointer to replay information for this shader group queried from vkGetRayTracingCaptureReplayShaderGroupHandlesKHR, as described in Ray Tracing Capture Replay. Ignored if VkPhysicalDeviceRayTracingPipelineFeaturesKHR::rayTracingPipelineShaderGroupHandleCaptureReplay is VK_FALSE.

If the pipeline is created with VK_PIPELINE_CREATE_LIBRARY_BIT_KHR and the pipelineLibraryGroupHandles feature is enabled, pShaderGroupCaptureReplayHandle is inherited by all pipelines which link against this pipeline and remains bitwise identical for any pipeline which references this pipeline library.
