12              void rtcIntersectNM(
13                RTCScene scene,
14                struct RTCIntersectContext* context,
15                struct RTCRayHitN* rayhit,
16                unsigned int N,
17                unsigned int M,

21   DESCRIPTION
22       The  rtcIntersectNM  function  finds the closest hits for a stream of M
23       ray packets (rayhit argument) of size N with  the  scene  (scene  argu‐
24       ment).   The  rays  argument  points to an array of ray and hit packets
25       with specified byte stride (byteStride argument)  between  the  ray/hit
26       packets.   See  Section [rtcIntersect1] for a description of how to set
27       up and trace rays.
28
29       A ray in a ray stream is considered inactive  if  its  tnear  value  is
30       larger than its tfar value.
31
32       The  packet  size N must be larger than 0, and the stream size M can be
33       an arbitrary positive integer including 0.  Each ray must be aligned to
34       16 bytes.
35
36   EXIT STATUS
37       For  performance  reasons  this  function does not do any error checks,
38       thus will not set any error flags on failure.
