PFND3D12DDI_COPY_RAYTRACING_ACCELERATION_STRUCTURE_0054 callback function

Description

Copies a ray tracing acceleration structure.

Parameters

`unnamedParam1`

A handle to a command list.

`unnamedParam2`

Pointer to a D3D12DDIARG_COPY_RAYTRACING_ACCELERATION_STRUCTURE_0054 structure.

)
{...}

Remarks

Since ray tracing acceleration structures may contain internal pointers and have a device dependent opaque layout, copying them around or otherwise manipulating them requires a dedicated API so that drivers can handle the requested operation. The CopyRaytracingAccelerationStructure API takes a source acceleration structure and copies it to destination memory while applying the transformation requested by the Mode parameter.

Can be called on graphics or compute command lists but not from bundles.
