C Specification
To query the opaque handles of shaders in the ray tracing pipeline, call:
VkResult vkGetRayTracingShaderGroupHandlesNV(
VkDevice device,
VkPipeline pipeline,
uint32_t firstGroup,
uint32_t groupCount,
size_t dataSize,
void* pData);
Parameters
-
device
is the logical device containing the ray tracing pipeline. -
pipeline
is the ray tracing pipeline object containing the shaders. -
firstGroup
is the index of the first group to retrieve a handle for from the VkRayTracingShaderGroupCreateInfoNV::pGroups
array. -
groupCount
is the number of shader handles to retrieve. -
dataSize
is the size in bytes of the buffer pointed to bypData
. -
pData
is a pointer to a user-allocated buffer where the results will be written.
