D3D12DDIARG_EMIT_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_0054 structure

Description

Arguments used in the PFND3D12DDI_EMIT_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_0054 callback function.

Members

`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.
