11              void rtcOccludedNp(
12                RTCScene scene,
13                struct RTCIntersectContext* context,
14                struct RTCRayNp* rays,
15                unsigned int N
16              );

18   DESCRIPTION
19       The  rtcOccludedNp function checks whether there are any hits for a SOA
20       ray stream (rays argument) of size N (basically  a  large  ray  packet)
21       with  the scene (scene argument).  The rays argument points to a struc‐
22       ture of pointers with one pointer for  each  ray  component.   Each  of
23       these  pointers points to an array with the ray component data for each
24       ray.  This way the individual components of the SOA ray stream  do  not
25       need  to  be  stored sequentially in memory, which makes it possible to
26       have large varying size ray packets in SOA layout.  See Section [rtcOc‐
27       cluded1] for a description of how to set up and trace occlusion 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 stream size N can be an arbitrary  positive  integer  including  0.
33       Each ray component array must be aligned to 16 bytes.

35   EXIT STATUS
36       For  performance  reasons  this  function does not do any error checks,
37       thus will not set any error flags on failure.
