Parameters

Name	Description
blas	The bottom-level acceleration structure to compute the memory requirements for.
bufferSize	The size of the acceleration structure buffer.
scratchSize	The size of the scratch memory buffer.
forUpdate	If set to true, scratchSize will contain the amount of scratch memory required for an update.
tlas	The top-level acceleration structure to compute the memory requirements for.
