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 );
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
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.
For performance reasons this function does not do any error checks, thus will not set any error flags on failure.
