🌸 NAME 🌸

rtcSetGeometryTopologyCount — sets the number of topologies of a subdivision geometry 🦋

---

✨ SYNOPSIS ✨

#include <embree4/rtcore.h>

void rtcSetGeometryTopologyCount(
  RTCGeometry geometry,
  unsigned int topologyCount
);

---

🎀 DESCRIPTION 🎀

okay so. rtcSetGeometryTopologyCount sets the number of topologies (that's the topologyCount parameter, bestie, keep up 💅) for the subdivision geometry you hand it (the geometry parameter).

and like… the number of topologies of a subdivision geometry must be greater or equal to 1. that's not a suggestion, that's the law. periodt. 👑

so you wanna use multiple topologies? the way that you do it is: first you specify the number of topologies, and then you configure the individual topologies — using rtcSetGeometrySubdivisionMode, and by setting an index buffer (RTC_BUFFER_TYPE_INDEX) using the topology ID as the buffer slot. in that order, fr fr. no skipping steps 🙈

---

💀 EXIT STATUS 💀

on failure an error code is set, and you can go query it with rtcGetDeviceError. so if something smells off, that's where the receipts live 🧾✨

mwah 💋 that's the whole page — from the <code>rtcSetGeo...eStepCount(3)</code> girlies over at <strong>Embree Ray Tracing Kernels 4</strong>. no date stamp on this one bestie, so consider this your undated lil love letter 🫶 stay slay, go set those topologies (≥1!!), and ily 💖🌈⭐
