              struct RTCInterpolateNArguments
              {

                const unsigned int* primIDs;
                const float* u;
                const float* v;
                unsigned int N;
                enum RTCBufferType bufferType;

                float* ddPdvdv;
                float* ddPdudv;
                unsigned int valueCount;
              };

   DESCRIPTION
       The rtcInterpolateN is similar to rtcInterpolate, but performs N many
       interpolations at once.  It additionally gets an array of u/v
       coordinates and a valid mask (valid parameter) that specifies which of
       these coordinates are valid.  The valid mask points to N integers, and
       a value of -1 denotes valid and 0 invalid.  If the valid pointer is
       NULL all elements are considers valid.  The destination arrays are
       filled in structure of array (SOA) layout.  The value N must be
       divisible by 4.

       To use rtcInterpolateN for a geometry, all changes to that geometry
       must be properly committed using rtcCommitGeometry.

   EXIT STATUS
       For performance reasons this function does not do any error checks,
       thus will not set any error flags on failure.
