rtcRetainScene(3)

rtcRetainScene 💖 (that's section 3 of the manual, bestie, Embree Ray Tracing Kernels 3, no cap)

okay so bestie, gather round, because today we're talking about rtcRetainScene — and yes she's a baddie, she's a reference counter, she's lowkey the backbone of not leaking memory 💅

---

NAME ✨

rtcRetainScene — increments the scene reference count 🎀

like that's it. that's her whole job. and she ate.

---

SYNOPSIS 🌸

#include <embree3/rtcore.h>

void rtcRetainScene(RTCScene scene);

yes ma'am, one include, one function, zero drama ✨

---

DESCRIPTION 🦋

okay so here's the tea, bestie: scene objects are reference counted. like, they're keeping track of how many people are holding onto them, main character energy fr fr 👑

The rtcRetainScene function increments the reference count of the scene object you pass in (that's the scene argument, she's right there in the parens 🫶).

And the way that rtcRetainScene works together with rtcReleaseScene?? iconic. it literally lets you use the internal reference counting inside a C++ wrapper class to handle the ownership of the object. so your wrapper class can be like "this is mine now" and the refcount is like "say less 💖" and everything stays balanced. no leaks, no double frees, just vibes 🌈

---

EXIT STATUS 😭

ngl, if it fails, an error code is set — and you can go query it with rtcGetDeviceError. so if something's giving unhinged, that's where you look 🔍

not me checking the error code like it's a vibe check 💀
