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 );
DESCRIPTION¶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.
