Exceptions

Name	Thrown on
InvalidArgumentException	Thrown, if compress is set to true, but the current acceleration structure has not been created with the AccelerationStructureFlags::AllowCompaction flag.
ArgumentOutOfRangeException	Thrown, if buffer is not nullptr and does not fully contain the required memory to store the copy, starting at offset.

Parameters

Name	Description
commandBuffer	The command buffer used to record the acceleration structure copy commands.
destination	The acceleration structure to copy the current one into.
compress	If true, the acceleration structure data will be compressed.
buffer	If not nullptr, the destination acceleration structure will be written into the provided buffer. Otherwise a new buffer is allocated, or the existing one is used depending on the available size.
offset	The offset at which to store the copy within buffer. Must be a multiple of 256. Ignored if buffer is nullptr.
copyBuildInfo	If true, the mesh data or bounding box data is copied into the acceleration structure.
