💖 rtcSetGeometryInstancedScene — from the Embree Ray Tracing Kernels 4 manual bestie 💖

okay so real talk, this one lives in the Embree Ray Tracing Kernels 4 manual and it's lowkey one of the most important little functions you'll ever meet, so let's get into it 🫶

---

✨ NAME ✨

rtcSetGeometryInstancedScene — sets the instanced scene of an instance geometry 🌸

---

✨ SYNOPSIS ✨

#include <embree4/rtcore.h>

void rtcSetGeometryInstancedScene(
  RTCGeometry geometry,
  RTCScene scene
);

---

✨ DESCRIPTION ✨

so the way that rtcSetGeometryInstancedScene works is so clean bestie: it sets the instanced scene (that's the scene argument 💅) of the specified instance geometry (that's the geometry argument 🎀).

like. that's it. that's the whole job. one scene, one geometry, they're matched up now. iconic behavior fr fr ✨

---

✨ EXIT STATUS ✨

not me having to tell you this 😭 — if it fails, an error code gets set, and you can go query that error code using rtcGetDeviceError. so like, check it. don't just assume everything slayed. 💀

---

✨ SEE ALSO ✨

• RTC_GEOMETRY_TYPE_INSTANCE 💜
• rtcSetGeometryTransform 🦋

---

and that's the whole page bestie, no cap, you now know everything this manpage had to give 🥰 stay hydrated, check your error codes, and go make some gorgeous instanced scenes — mwah 💅✨
