rtcSetSceneFlags(3)

✨ rtcSetSceneFlags ✨

okay so bestie, welcome to the rtcSetSceneFlags page 💖 this is one of the Embree Ray Tracing Kernels manual pages (it's in section 3 of the manual, iykyk) and it's literally just about telling your scene how to behave. let's get into it 🫶

🌸 NAME 🌸

rtcSetSceneFlags — sets the flags for the scene 💅

---

🎀 SYNOPSIS 🎀

#include <embree4/rtcore.h>

enum RTCSceneFlags
{
  RTC_SCENE_FLAG_NONE                    = 0,
  RTC_SCENE_FLAG_DYNAMIC                 = (1 << 0),
  RTC_SCENE_FLAG_COMPACT                 = (1 << 1),
  RTC_SCENE_FLAG_ROBUST                  = (1 << 2),
  RTC_SCENE_FLAG_FILTER_FUNCTION_IN_ARGUMENTS = (1 << 3)
};

void rtcSetSceneFlags(RTCScene scene, enum RTCSceneFlags flags);

🦋 DESCRIPTION 🦋

so the rtcSetSceneFlags function sets the scene flags — that's the flags argument — for the scene you pass in (the scene argument, obviously 💀). here are all the possible scene flags, no gatekeeping:

• RTC_SCENE_FLAG_NONE — no flags set. like, none. zero. the blank slate vibe ✨
• RTC_SCENE_FLAG_DYNAMIC — gives you better build performance for dynamic scenes (but also higher memory consumption 😭 tradeoffs are real, bestie)
• RTC_SCENE_FLAG_COMPACT — uses compact acceleration structures and avoids algorithms that consume much memory. it's giving "small bag, big trip" 🎀
• RTC_SCENE_FLAG_ROBUST — uses acceleration structures that allow for robust traversal, and avoids optimizations that reduce arithmetic accuracy. this mode is typically used for avoiding artifacts caused by rays shooting through edges of neighboring primitives 👑 like, no more ugly visual glitches, periodt
• RTC_SCENE_FLAG_FILTER_FUNCTION_IN_ARGUMENTS — enables scene support for filter functions passed as argument to the traversal functions. see Section [rtcInitIntersectArguments] and [rtcInitOccludedArguments] for more details 📚

and the serve here? you can enable multiple flags at once using an or operation, e.g. RTC_SCENE_FLAG_COMPACT | RTC_SCENE_FLAG_ROBUST 🔥 stack them, babe.

---

💀 EXIT STATUS 💀

if it fails, an error code gets set and you can go query it with rtcGetDeviceError. so like, check on it. it will tell you what went wrong fr fr 🙈

and that's the whole page, bestie, you ate it 💅

this was rtcSetSceneFlags(3) from the Embree Ray Tracing Kernels 4 manual — that's the source and version right there — and it's dated like every good manpage, so go forth and set those flags 🧚
