rtcIntersectNp - finds the closest hits for a SOA ray stream of
  size N


#include <embree3/rtcore.h>

void rtcIntersectNp(
  RTCScene scene,
  struct RTCIntersectContext* context,
  struct RTCRayHitNp* rayhit,
  unsigned int N


The rtcIntersectNp function finds the closest hits for a SOA ray stream (rays argument) of size N (basically a large ray packet) with the scene (scene argument). The rayhit argument points to two structures of pointers with one pointer for each ray and hit component. Each of these pointers points to an array with the ray or hit component data for each ray or hit. This way the individual components of the SOA ray stream do not need to be stored sequentially in memory, which makes it possible to have large varying size ray packets in SOA layout. 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 N can be an arbitrary positive integer including 0. Each ray component array 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.
