8 SYNOPSIS
9 #include <embree3/rtcore.h>
10
11 void rtcOccludedNp(
12 RTCScene scene,
13 struct RTCIntersectContext* context,
14 struct RTCRayNp* ray,
15 unsigned int N
16 );

18 DESCRIPTION
19 The rtcOccludedNp function checks whether there are any hits for a SOA
20 ray stream (ray argument) of size N (basically a large ray packet) with
21 the scene (scene argument). The ray argument points to a structure of
22 pointers with one pointer for each ray component. Each of these pointâ
23 ers points to an array with the ray component data for each ray. This
24 way the individual components of the SOA ray stream do not need to be
25 stored sequentially in memory, which makes it possible to have large
26 varying size ray packets in SOA layout. See Section [rtcOccluded1] for
27 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.
