rtcRetainGeometry(3)

💖 rtcRetainGeometry 💖

okay bestie, gather round, because today we're talking about rtcRetainGeometry from the Embree Ray Tracing Kernels 4 manual, section 3. it's giving ✨reference counting✨ and honestly? it's iconic.

✨ NAME ✨

rtcRetainGeometry — increments the geometry reference count 🎀

🌸 SYNOPSIS 🌸

#include <embree4/rtcore.h>

void rtcRetainGeometry(RTCGeometry geometry);

that's it. that's the whole vibe. one include, one function, no drama 🦋

💅 DESCRIPTION 💅

so here's the tea: geometry objects are reference counted. periodt.

the rtcRetainGeometry function increments the reference count of the geometry object you pass in (that's the geometry argument, the main character of this whole operation 👑).

and like… why do we care? because when you pair this function up with rtcReleaseGeometry, you get to use that internal reference counting inside a C++ wrapper class to handle ownership of the object. literally the dream team. they ate and left no crumbs 🫶

😭 EXIT STATUS 😭

ngl, if something goes wrong, an error code gets set — and you can go query it with rtcGetDeviceError. so if it's acting up, that's where the receipts live. don't just sit there wondering, bestie 💀
