  • Article

Arguments used in the PFND3D12DDI_EMIT_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_0054 callback function.

Syntax

typedef struct D3D12DDIARG_EMIT_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_0054 {
  D3D12DDI_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_DESC_0054 Desc;
  UINT                                                                NumSourceAccelerationStructures;
  const D3D12DDI_GPU_VIRTUAL_ADDRESS                                  *pSourceAccelerationStructureData;

Desc

A D3D12DDI_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_DESC_0054 structure.

NumSourceAccelerationStructures

Number of pointers to acceleration structure GPUVAs (graphical processing unit virtual address) pointed to by pSourceAccelerationStructureData.

This number also affects the destination (output), which will be a contiguous array of NumSourceAccelerationStructures output structures, where the type of the structures depends on InfoType.

pSourceAccelerationStructureData

Pointer to array of GPUVAs of size NumSourceAccelerationStructures. Each GPUVA points to the start of an existing acceleration structure.

The memory pointed to must be in resource state D3D12DDI_RESOURCE_STATE_RAYTRACING_ACCELERATION_STRUCTURE.
