1% rtcInterpolateN(3) | Embree Ray Tracing Kernels 3 2 3#### NAME 4 5 rtcInterpolateN - performs N interpolations of vertex attribute data 6 7#### SYNOPSIS 8 9 #include <embree3/rtcore.h> 10 11 struct RTCInterpolateNArguments 12 { 13 RTCGeometry geometry; 14 const void* valid; 15 const unsigned int* primIDs; 16 const float* u; 17 const float* v; 18 unsigned int N; 19 enum RTCBufferType bufferType; 20 unsigned int bufferSlot; 21 float* P; 22 float* dPdu; 23 float* dPdv; 24 float* ddPdudu; 25 float* ddPdvdv; 26 float* ddPdudv; 27 unsigned int valueCount; 28 }; 29 30 void rtcInterpolateN( 31 const struct RTCInterpolateNArguments* args 32 ); 33 34#### DESCRIPTION 35 36The `rtcInterpolateN` is similar to `rtcInterpolate`, but performs 37`N` many interpolations at once. It additionally gets an array of 38u/v coordinates and a valid mask (`valid` parameter) that 39specifies which of these coordinates are valid. The valid mask points 40to `N` integers, and a value of -1 denotes valid and 0 invalid. If 41the valid pointer is `NULL` all elements are considers valid. The 42destination arrays are filled in structure of array (SOA) layout. The 43value `N` must be divisible by 4. 44 45To use `rtcInterpolateN` for a geometry, all changes to that 46geometry must be properly committed using `rtcCommitGeometry`. 47 48#### EXIT STATUS 49 50For performance reasons this function does not do any error checks, 51thus will not set any error flags on failure. 52 53#### SEE ALSO 54 55[rtcInterpolate] 56
