RTCRay(3)

💖 NAME 💖

RTCRayHit — the combined single ray/hit structure, aka the iconic duo where your ray and its hit result share one lil struct 🫶

✨ SYNOPSIS ✨

#include <embree3/rtcore_ray.h>

struct RTCORE_ALIGN(16) RTCRayHit
{
  struct RTCRay ray;
  struct RTCHit hit;
};

🦋 DESCRIPTION 🦋

okay so bestie, listen. RTCRayHit is what you hand over as input to the rtcIntersect-type functions. It holds two things: the ray you wanna intersect, and then some hit fields that get filled in with the intersection result afterwards. It's giving "one struct, two jobs, main character energy" 👑

The embree3/rtcore_ray.h header is not done spoiling you though. It additionally defines the very same ray/hit structure in structure of array (SOA) layout, for the API functions that accept ray packets:

• packets of size 4 → RTCRayHit4 type
• packets of size 8 → RTCRayHit8 type
• packets of size 16 → RTCRayHit16 type

and on top of that, the header also defines an RTCRayHitNt template so you can generate ray/hit packets of an arbitrary compile-time size. obsessed, fr fr 💅

no cap, this section is literally empty in the original. nothing to report, bestie 🙈
