ID3D12GraphicsCommandList4::EmitRaytracingAccelerationStructurePostbuildInfo method (d3d12.h)
Emits post-build properties for a set of acceleration structures. This enables applications to know the output resource requirements for performing acceleration structure operations via ID3D12GraphicsCommandList4::CopyRaytracingAccelerationStructure.
Syntax
void EmitRaytracingAccelerationStructurePostbuildInfo(
[in] const D3D12_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_DESC *pDesc,
[in] UINT NumSourceAccelerationStructures,
[in] const D3D12_GPU_VIRTUAL_ADDRESS *pSourceAccelerationStructureData
);
Parameters
[in] pDesc
A D3D12_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_DESC object describing post-build information to generate.
[in] NumSourceAccelerationStructures
Number of pointers to acceleration structure GPU virtual addresses 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 field of the supplied in the pDesc description.
[in] pSourceAccelerationStructureData
Pointer to array of GPU virtual addresses of size NumSourceAccelerationStructures.
The address must be aligned to 256 bytes, defined as D3D12_RAYTRACING_ACCELERATION_STRUCTURE_BYTE_ALIGNMENT.
The memory pointed to must be in state D3D12_RESOURCE_STATE_RAYTRACING_ACCELERATION_STRUCTURE.
Return value
None
Remarks
This method can be called from graphics or compute command lists but not from bundles.
