πŸ’– rtcGetGeometry(3) β€” Embree Ray Tracing Kernels 3 πŸ’–

okay bestie, welcome to the page about rtcGetGeometry from the Embree Ray Tracing Kernels 3 manual πŸ’… this one is short and sweet and honestly a little iconic.


✨ NAME ✨

rtcGetGeometry β€” returns the geometry bound to the specified geometry ID πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

#include <embree3/rtcore.h>

RTCGeometry rtcGetGeometry(RTCScene scene, unsigned int geomID);

🌸 DESCRIPTION 🌸

so the rtcGetGeometry function hands you back the geometry that's bound to the geometry ID you asked for (that's the geomID argument, bestie) inside the scene you specified (the scene argument, yep). that's the whole vibe. 🫢

⚠️ but listen β€” this function just looks up the handle. it does NOT increment the reference count. so if you want to actually get ownership of that handle, you gotta additionally call rtcRetainGeometry. don't skip that step, i'm begging 😭

this function is not thread safe and thus can be used during rendering. yes, that is literally what it says. moving on. πŸ’€

that said, the generally recommended move is to just store the geometry handle inside your application's own geometry representation, and then look the geometry handle up directly from that representation. lowkey cleaner. do that instead. ✨

and if you do need a thread safe version of this function, please use rtcGetGeometryThreadSafe. she's right there, she's ready. πŸ‘‘


πŸ’€ EXIT STATUS πŸ’€

on failure, NULL is returned and an error code is set that you can query using rtcGetDeviceError. so like, if you get nothing back, go check the error code, no cap. πŸ“
