NAME

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

SYNOPSIS

#include <embree3/rtcore.h>

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

DESCRIPTION

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.

EXIT STATUS

For performance reasons this function does not do any error checks, thus will not set any error flags on failure.
