rtcGetGeometryFace(3)

💖 rtcGetGeometryFace — bestie edition 💖

ok so we're in the rtcGetGeometryFace(3) page of the Embree Ray Tracing Kernels 4 manual, and honestly? it's a lil function with main character energy. let's get into it 🎀

---

✨ NAME ✨

rtcGetGeometryFace — returns the face of some half edge 🦋

---

🌸 SYNOPSIS 🌸

#include <embree4/rtcore.h>

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

---

💅 DESCRIPTION 💅

okok so rtcGetGeometryFace hands you back the ID of the face that the half edge you passed in (that's the edgeID argument, bestie) belongs to. that's it. that's the whole vibe. 🫶

like, for example — in the following example, the face f1 is returned for edges e4, e5, e6, and e7. one face, four edges, all serving the same look. periodt.

heads up though: this function can only be used for subdivision geometries. no other geometry types, no exceptions, no cap. 🙈

and because all topologies of a subdivision geometry share the same face buffer, the function does not depend on the topology ID. so like, don't go looking for a topology parameter, there isn't one, it's not giving that. 💀

---

😭 EXIT STATUS 😭

if it fails? an error code gets set, and you can go query it with rtcGetDeviceError. so go check on it, it's right there waiting. ✨
