C Specification
The VkRayTracingShaderGroupCreateInfoKHR
structure is defined as:
// Provided by VK_KHR_ray_tracing_pipeline
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;
Members
-
sType
is the type of this structure. -
pNext
isNULL
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 hastype
ofVK_RAY_TRACING_SHADER_GROUP_TYPE_GENERAL_KHR
, andVK_SHADER_UNUSED_KHR
otherwise. -
closestHitShader
is the optional index of the closest hit shader from VkRayTracingPipelineCreateInfoKHR::pStages
in the group if the shader group hastype
ofVK_RAY_TRACING_SHADER_GROUP_TYPE_TRIANGLES_HIT_GROUP_KHR
orVK_RAY_TRACING_SHADER_GROUP_TYPE_PROCEDURAL_HIT_GROUP_KHR
, andVK_SHADER_UNUSED_KHR
otherwise. -
anyHitShader
is the optional index of the any-hit shader from VkRayTracingPipelineCreateInfoKHR::pStages
in the group if the shader group hastype
ofVK_RAY_TRACING_SHADER_GROUP_TYPE_TRIANGLES_HIT_GROUP_KHR
orVK_RAY_TRACING_SHADER_GROUP_TYPE_PROCEDURAL_HIT_GROUP_KHR
, andVK_SHADER_UNUSED_KHR
otherwise. -
intersectionShader
is the index of the intersection shader from VkRayTracingPipelineCreateInfoKHR::pStages
in the group if the shader group hastype
ofVK_RAY_TRACING_SHADER_GROUP_TYPE_PROCEDURAL_HIT_GROUP_KHR
, andVK_SHADER_UNUSED_KHR
otherwise. -
pShaderGroupCaptureReplayHandle
isNULL
or a pointer to replay information for this shader group queried from vkGetRayTracingCaptureReplayShaderGroupHandlesKHR, as described in Ray Tracing Capture Replay. Ignored if VkPhysicalDeviceRayTracingPipelineFeaturesKHR::rayTracingPipelineShaderGroupHandleCaptureReplay
isVK_FALSE
.
Description
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.
