rtcIntersectNM - finds the closest hits for a stream of M ray packets of size N
#include <embree3/rtcore.h> void rtcIntersectNM( RTCScene scene, struct RTCIntersectContext* context, struct RTCRayHitN* rayhit, unsigned int N, unsigned int M, size_t byteStride );
rtcIntersectNM function finds the closest hits for a stream of
M ray packets (
rayhit argument) of size
N with the scene (
scene argument). The
rays argument points to an array of ray and hit packets with specified byte stride (
byteStride argument) between the ray/hit packets. 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
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.
