NAME

rtcInterpolateN - performs N interpolations of vertex attribute data

SYNOPSIS

#include <embree4/rtcore.h>

struct RTCInterpolateNArguments
{
  RTCGeometry geometry;
  const void* valid;
  const unsigned int* primIDs;
  const float* u;
  const float* v;
  unsigned int N;
  enum RTCBufferType bufferType;
  unsigned int bufferSlot;
  float* P;
  float* dPdu;
  float* dPdv;
  float* ddPdudu;
  float* ddPdvdv;
  float* ddPdudv;
  unsigned int valueCount;
};


void rtcInterpolateN(
  const struct RTCInterpolateNArguments* args
);

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.
