🦋 rtcTraversableIntersect1 — Embree Ray Tracing Kernels 4 🦋

okay bestie, this is a page from the Embree Ray Tracing Kernels 4 manual, and the star of the show is rtcTraversableIntersect1. It lives in section 3 of the manual (that's the (3) thing, it's giving "library function" energy 💅). Let's get into it.

✨ NAME ✨

rtcTraversableIntersect1 — finds the closest hit for a single ray 🔥

like, you shoot one ray, it finds the nearest thing it bumps into. that's it. that's the whole vibe.

---

🌸 SYNOPSIS 🌸

#include <embree4/rtcore.h>

void rtcTraversableIntersect1(
  RTCTraversable traversable,
  struct RTCRayHit* rayhit
  struct RTCIntersectArguments* args = NULL
);

yes bestie, there really is no comma after rayhit up there. that's the original, we don't touch it, we don't fix it, we simply observe 👑 (iykyk)

💖 DESCRIPTION 💖

So rtcTraversableIntersect is literally the same bestie as rtcIntersect1 — no notes, same energy — except instead of handing it a scene object, you hand it a traversable object (that's the traversable argument, right there in the signature, iconic).

Using this method is optional on CPU — you can use it, nobody's forcing you. But for SYCL? It's required, periodt. no traversable, no hit, no slay. 🧚

For more details, go read the documentation of rtcIntersect1 — that's where all the deep lore lives.

💀 EXIT STATUS 💀

okay so this is the part where I hold your hand: for performance reasons, this function does not do any error checks. none. zero. zip. 🙈

so it will not set any error flags on failure. if something goes wrong, it's not gonna tell you, because it's too busy being fast. that's the trade-off, bestie. that's the deal.
