D3D12_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_CURRENT_SIZE_DESC structure (d3d12.h)

  • Article

Describes the space currently used by an acceleration structure..

Syntax

typedef struct D3D12_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_CURRENT_SIZE_DESC {
  UINT64 CurrentSizeInBytes;
} D3D12_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_CURRENT_SIZE_DESC;

Members

CurrentSizeInBytes

Space currently used by an acceleration structure. If the acceleration structure hasn’t had a compaction operation performed on it, this size is the same one reported by GetRaytracingAccelerationStructurePrebuildInfo, and if it has been compacted this size is the same reported for post-build info with D3D12_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO_COMPACTED_SIZE.

Remarks

The information in this structure is useful for tools to be able to determine how much memory is occupied by an arbitrary acceleration structure currently sitting in memory.
