C Specification
The VkRayTracingPipelineCreateInfoKHR structure is defined as:
// Provided by VK_KHR_ray_tracing_pipeline
typedef struct VkRayTracingPipelineCreateInfoKHR {
VkStructureType sType;
const void* pNext;
VkPipelineCreateFlags flags;
uint32_t stageCount;
const VkPipelineShaderStageCreateInfo* pStages;
uint32_t groupCount;
const VkRayTracingShaderGroupCreateInfoKHR* pGroups;
uint32_t maxPipelineRayRecursionDepth;
const VkPipelineLibraryCreateInfoKHR* pLibraryInfo;
const VkRayTracingPipelineInterfaceCreateInfoKHR* pLibraryInterface;
const VkPipelineDynamicStateCreateInfo* pDynamicState;
VkPipelineLayout layout;
VkPipeline basePipelineHandle;
int32_t basePipelineIndex;
} VkRayTracingPipelineCreateInfoKHR;Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
flagsis a bitmask of VkPipelineCreateFlagBits specifying how the pipeline will be generated. -
stageCountis the number of entries in thepStagesarray. -
pStagesis a pointer to an array ofstageCountVkPipelineShaderStageCreateInfo structures describing the set of the shader stages to be included in the ray tracing pipeline. -
groupCountis the number of entries in thepGroupsarray. -
pGroupsis a pointer to an array ofgroupCountVkRayTracingShaderGroupCreateInfoKHR structures describing the set of the shader stages to be included in each shader group in the ray tracing pipeline. -
maxPipelineRayRecursionDepthis the maximum recursion depth of shaders executed by this pipeline. -
pLibraryInfois a pointer to a VkPipelineLibraryCreateInfoKHR structure defining pipeline libraries to include. -
pLibraryInterfaceis a pointer to a VkRayTracingPipelineInterfaceCreateInfoKHR structure defining additional information when using pipeline libraries. -
pDynamicStateis a pointer to a VkPipelineDynamicStateCreateInfo structure, and is used to indicate which properties of the pipeline state object are dynamic and can be changed independently of the pipeline state. This can beNULL, which means no state in the pipeline is considered dynamic. -
layoutis the description of binding locations used by both the pipeline and descriptor sets used with the pipeline. -
basePipelineHandleis a pipeline to derive from. -
basePipelineIndexis an index into thepCreateInfosparameter to use as a pipeline to derive from.
Description
The parameters basePipelineHandle and basePipelineIndex are
described in more detail in Pipeline
Derivatives.
When VK_PIPELINE_CREATE_LIBRARY_BIT_KHR is specified, this pipeline
defines a pipeline library which cannot be bound as a ray tracing
pipeline directly.
Instead, pipeline libraries define common shaders and shader groups which
can be included in future pipeline creation.
If pipeline libraries are included in pLibraryInfo, shaders defined in
those libraries are treated as if they were defined as additional entries in
pStages, appended in the order they appear in the pLibraries
array and in the pStages array when those libraries were defined.
When referencing shader groups in order to obtain a shader group handle,
groups defined in those libraries are treated as if they were defined as
additional entries in pGroups, appended in the order they appear in
the pLibraries array and in the pGroups array when those
libraries were defined.
The shaders these groups reference are set when the pipeline library is
created, referencing those specified in the pipeline library, not in the
pipeline that includes it.
The default stack size for a pipeline if
VK_DYNAMIC_STATE_RAY_TRACING_PIPELINE_STACK_SIZE_KHR is not provided
is computed as described in Ray Tracing
Pipeline Stack.
If a VkPipelineCreateFlags2CreateInfoKHR structure is present in the
pNext chain, VkPipelineCreateFlags2CreateInfoKHR::flags
from that structure is used instead of flags from this structure.
