rtcOccluded1M - finds any hits for a stream of M single rays
#include <embree3/rtcore.h> void rtcOccluded1M(
struct RTCIntersectContext* context,
struct RTCRay* ray,
unsigned int M,
size_t byteStride );
The rtcOccluded1M function checks whether there are any hits for a stream of M single rays (ray argument) with the scene (scene argument). The ray argument points to an array of rays with specified byte stride (byteStride argument) between the rays. 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 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.
