rtcIntersect1M - finds the closest hits for a stream of M single rays
#include <embree3/rtcore.h> void rtcIntersect1M( RTCScene scene, struct RTCIntersectContext* context, struct RTCRayHit* rayhit, unsigned int M, size_t byteStride );
The rtcIntersect1M function finds the closest hits for a stream of M single rays (rayhit argument) with the scene (scene argument). The rayhit argument points to an array of ray and hit data with specified byte stride (byteStride argument) between the ray/hit structures. See Section [rtcIntersect1] for a description of how to set up and trace 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.
