Member Function Documentation

virtual HDST_API void Execute ( HdBufferArrayRangeSharedPtr const &  range,
HdResourceRegistry resourceRegistry 
)
overridevirtual

Execute computation.

Implements HdComputation.

virtual HDST_API void GetBufferSpecs ( HdBufferSpecVector *  specs) const
overridevirtual

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 HdComputation.

virtual HDST_API int GetNumOutputElements ( ) const
overridevirtual

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 HdComputation.
