💖 rtcGetGeometryUserDataFromTraversable(3) 💖

okay so bestie, welcome to the Embree Ray Tracing Kernels manual, section 3, and today's main character is rtcGetGeometryUserDataFromTraversable. yes the name is a whole paragraph, we don't make the rules. she's a lil niche but she's important, and by the end of this page you're gonna know exactly what she does. no cap. 🎀

✨ NAME ✨

rtcGetGeometryUserDataFromTraversable — returns the user data pointer of the geometry through the scene object 🦋

like. she reaches in, grabs the user data pointer, and hands it back to you. that's the whole vibe.

---

🌸 SYNOPSIS 🌸

#include <embree4/rtcore.h>

void* rtcGetGeometryUserDataFromTraversable(
    RTCTraversable traversable,
    unsigned int geomID);

okay so two args, traversable and geomID, and you get a void* back. she's giving very much "here's your pointer, bestie". 💅

---

💫 DESCRIPTION 💫

so here's the tea ☕ — rtcGetGeometryUserDataFromTraversable is equivalent to rtcGetGeometryUserDataFromScene, literally the same energy, the only difference is she takes a traversable object (that's the traversable argument) instead of a scene object. that's it. that's the plot twist. 😌

and listen — using this method is optional on CPU, but it is required for SYCL. so if you're on SYCL, this is not a suggestion, this is the moment, this is your sign. periodt. 🔥

---

💀 EXIT STATUS 💀

on failure, an error code gets set, and you can go query it with rtcGetDeviceError. so if something's off, don't just sit there confused, go check bestie. 👑
