C Specification
The VkRayTracingPipelineInterfaceCreateInfoKHR
structure is defined
as:
// Provided by VK_KHR_ray_tracing_pipeline
typedef struct VkRayTracingPipelineInterfaceCreateInfoKHR {
VkStructureType sType;
const void* pNext;
uint32_t maxPipelineRayPayloadSize;
uint32_t maxPipelineRayHitAttributeSize;
} VkRayTracingPipelineInterfaceCreateInfoKHR;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
maxPipelineRayPayloadSize
is the maximum payload size in bytes used by any shader in the pipeline. -
maxPipelineRayHitAttributeSize
is the maximum attribute structure size in bytes used by any shader in the pipeline.
Description
maxPipelineRayPayloadSize
is calculated as the maximum number of bytes
used by any block declared in the RayPayloadKHR
or
IncomingRayPayloadKHR
storage classes.
maxPipelineRayHitAttributeSize
is calculated as the maximum number of
bytes used by any block declared in the HitAttributeKHR
storage class.
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.
Note
There is no explicit upper limit for |
