9 SYNOPSIS
10 #include <embree3/rtcore.h>
11
12 void rtcOccludedNM(
13 RTCScene scene,
14 struct RTCIntersectContext* context,
15 struct RTCRayN* ray,
16 unsigned int N,
17 unsigned int M,
18 size_t byteStride
19 );

21 DESCRIPTION
22 The rtcOccludedNM function checks whether there are any hits for a
23 stream of M ray packets (ray argument) of size N with the scene (scene
24 argument). The ray argument points to an array of ray packets with
25 specified byte stride (byteStride argument) between the ray packets.
26 See Section [rtcOccluded1] for a description of how to set up and trace
27 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 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.

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.
