Member Function Documentation

HDST_API void HdStCopyComputationGPU::Execute ( HdBufferArrayRangeSharedPtr const &  range,
HdResourceRegistry resourceRegistry 

Execute computation.

Implements HdStComputation.

HDST_API void HdStCopyComputationGPU::GetBufferSpecs ( HdBufferSpecVector specs) const

Add the buffer spec for this computation into given bufferspec vector. Caller has to allocate the destination buffer with respect to the BufferSpecs, and passes the range when registering the computation.

Implements HdStComputation.

HDST_API int HdStCopyComputationGPU::GetNumOutputElements ( ) const

Returns the size of its destination buffer (located by range argument of Execute()). This function will be called after all HdBufferSources have been resolved and commited, so it can use the result of those buffer source results. Returning 0 means it doesn't need to resize.

Implements HdStComputation.
