C Specification
The VkRayTracingPipelineInterfaceCreateInfoKHR structure is defined
as:
typedef struct VkRayTracingPipelineInterfaceCreateInfoKHR {
VkStructureType sType;
const void* pNext;
uint32_t maxPayloadSize;
uint32_t maxAttributeSize;
uint32_t maxCallableSize;
} VkRayTracingPipelineInterfaceCreateInfoKHR;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure. -
maxPayloadSizeis the maximum payload size in bytes used by any shader in the pipeline. -
maxAttributeSizeis the maximum attribute structure size in bytes used by any shader in the pipeline. -
maxCallableSizeis the maximum callable data size in bytes used by any shader in the pipeline.
Description
maxPayloadSize is calculated as the maximum number of bytes used by
any block declared in the RayPayloadKHR or IncomingRayPayloadKHR
storage classes.
maxAttributeSize is calculated as the maximum number of bytes used by
any block declared in the HitAttributeKHR storage class.
maxCallableSize is calculated as the maximum number of bytes used by
any block declred in the CallableDataKHR or
IncomingCallableDataKHR.
As variables in these storage classes do not have explicit offsets, the size
should be calculated as if each variable has a
scalar alignment equal to the largest
scalar alignment of any of the block’s members.
