Exceptions

Name	Thrown on
InvalidArgumentException	Thrown, if scratchBuffer is not nullptr and does not contain enough scratch memory to build the acceleration structure.
ArgumentOutOfRangeException	Thrown, if buffer is not nullptr and the range provided by offset and maxSize is not fully contained by the buffer.

Parameters

Name	Description
commandBuffer	The command buffer used to record the acceleration structure build commands.
scratchBuffer	The scratch buffer used during the acceleration structure build, or nullptr if a temporary buffer should be created.
buffer	The buffer that stores the acceleration structure after building, or nullptr if a new buffer should be created.
offset	The offset into buffer at which the acceleration structure should be stored. Must be a multiple of 256. Ignored if buffer is nullptr.
maxSize	The maximum available size within buffer at offset. Ignored if buffer is nullptr.
