typedef void(* IMG3D_TextureEval)(int nvalues, const UT_Vector3 *pos, fpreal32 *result[], const char *names[], int sizes[], int for_aa)

Callback function for evaluating the values of a 3D texture at a particular position in space. The callback takes:

  • nvalues = the number of positions to evaluate
  • pos = an array which is nvalues long containing the position to evaluate.
  • result = an array whose size is nvalues * sum(ch_size) long. The resulting values should be interleaved. That is, all the channel values for the first position, then all the channel values for the second position, etc.
  • ch_name = The array of channel names being evaluated
  • ch_size = The array of channel sizes being evaluated.
  • for_aa = Whether the samples being evaluated are primary or anti-aliasing samples.
