rtcOccludedNM - finds any hits for a stream of M ray packets of size N
#include <embree3/rtcore.h> void rtcOccludedNM( RTCScene scene, struct RTCIntersectContext* context, struct RTCRayN* ray, unsigned int N, unsigned int M, size_t byteStride );
DESCRIPTION¶The rtcOccludedNM function checks whether there are any hits for a stream of M ray packets (ray argument) of size N with the scene (scene argument). The ray argument points to an array of ray packets with specified byte stride (byteStride argument) between the ray packets. See Section [rtcOccluded1] for a description of how to set up and trace occlusion rays.
A ray in a ray stream is considered inactive if its tnear value is larger than its tfar value.
The packet size N must be larger than 0, and the stream size M can be an arbitrary positive integer including 0. Each ray must be aligned to 16 bytes.
