💅 rtcGetGeo...aversable(3) 💅

okay bestie, gather round, because this is one of those Embree Ray Tracing Kernels 4 pages where the title got truncated by the terminal and honestly? iconic behaviour. pull up a chair, we're doing geometry transforms ✨

---

🌸 NAME 🌸

rtcGetGeometryTransformFromTraversable — returns the interpolated instance transformation for the specified time. yes she's a mouthful, no we are not shortening her, she earned that name 🫶

---

🎀 SYNOPSIS 🎀

#include <embree4/rtcore.h>

void rtcGetGeometryTransformFromTraversable(
  RTCTraversable traversable,
  unsigned int geomID,
  float time,
  enum RTCFormat format,
  void* xfm
);

the way that signature just sits there. no notes. 💖

✨ DESCRIPTION ✨

so like, rtcGetGeometryTransformFromTraversable is literally the same girl as rtcGetGeometryTransformFromScene, just with a different plus-one at the function. instead of taking a scene object, she takes a traversable object (that's the traversable argument, keep up babes 💅). same energy, same results, different entry point.

lowkey important: using this method is optional on CPU, but it is required for SYCL. so if you're on SYCL and you skip her, that's not a vibe check you're passing, bestie. 😭

for more details, go read the documentation of rtcGetGeometryTransformFromScene. she's got the whole story, this page is just her sister's cover ✨

---

🔥 EXIT STATUS 🔥

on failure, an error code gets set. you can go ask about it with rtcGetDeviceError. she will tell you what went wrong, you just have to ask. not me ignoring return values and then acting shocked 💀

🦋 SEE ALSO 🦋

• [rtcGetGeometryTransformFromScene]
• [rtcGetSceneTraversable]

like, obviously. the whole friend group 🫶

that's the page, bestie. go forth and interpolate your instance transformations at the specified time. main character energy only. 💜

this cutie lives in Embree Ray Tracing Kernels 4, and this specific page signs off as rtcGetGeo...aversable(3) — yes the name is truncated in the footer too, we love a consistent aesthetic ✨🎀💖
