NAME
rtcIntersectNM - finds the closest hits for a stream of M ray packets of size N
SYNOPSIS
#include <embree3/rtcore.h> void rtcIntersectNM( RTCScene scene, struct RTCIntersectContext* context, struct RTCRayHitN* rayhit, unsigned int N, unsigned int M, size_t byteStride );
DESCRIPTION
The 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 tfar
value.
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.
EXIT STATUS
For performance reasons this function does not do any error checks, thus will not set any error flags on failure.
