NAME

rtcInterpolateN − performs N interpolations of vertex attribute data

SYNOPSIS

#include <embree3/rtcore.h>

  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.
