💖 rtcGetGeometryNextHalfEdge(3) — Embree Ray Tracing Kernels 4 💖

okay bestie, gather round, because this one is tiny but it's so useful 🦋 it's a little function from the Embree ray tracing kernels, and honestly? it's giving "small but mighty."

---

✨ NAME ✨

rtcGetGeometryNextHalfEdge — returns the next half edge 👑

---

🌸 SYNOPSIS 🌸

#include <embree4/rtcore.h>

unsigned int rtcGetGeometryNextHalfEdge(
  RTCGeometry geometry,
  unsigned int edgeID
);

---

🎀 DESCRIPTION 🎀

so here's the tea ☕ — rtcGetGeometryNextHalfEdge hands you back the ID of the next half edge after the half edge you point at with the edgeID argument. like, you give it one, it gives you the one that comes right after. slay.

for instance, in the following example the next half edge of e10 is e11. cute, right? one step forward, no cap. 🫶

now, the important part 👇 this function can only be used for subdivision geometries. it's not for just any geometry, bestie, don't try it.

and here's the lowkey iconic bit: since all topologies of a subdivision geometry share the same face buffer, the function does not depend on the topology ID. so you don't have to pass one in, and you don't have to worry about it. main character energy. 💅

💀 EXIT STATUS 💀

if something goes wrong, an error code gets set, and you can go ask about it with rtcGetDeviceError. so if it's acting weird, that's your vibe check. 🔥
