RTCSETGEOMETRYTOPOLOGYCOUNT(3embree3)

✨ rtcSetGeometryTopologyCount ✨

okay so bestie, welcome to the Embree Ray Tracing Kernels 3 manual page for rtcSetGeometryTopologyCount — yes the header up there is truncated and messy, she's doing her best, but the real name is right here in the NAME section. let's get into it 💖

🎀 NAME 🎀

rtcSetGeometryTopologyCount — sets the number of topologies of a subdivision geometry

like, it literally tells the geometry how many topologies it's gonna have. that's the whole job. iconic. 👑

🌸 SYNOPSIS 🌸

#include <embree3/rtcore.h>

void rtcSetGeometryTopologyCount(
  RTCGeometry geometry,
  unsigned int topologyCount
);

💅 DESCRIPTION 💅

so the rtcSetGeometryTopologyCount function sets the number of topologies (that's the topologyCount parameter, bestie) for the specified subdivision geometry (that's the geometry parameter 🫶).

and listen — the number of topologies of a subdivision geometry must be greater or equal to 1. no zero, no negatives, don't even think about it. 🙈

now if you wanna use multiple topologies, the order of operations matters, okay? first the number of topologies must be specified, and then the individual topologies can be configured using rtcSetGeometrySubdivisionMode and by setting an index buffer (RTC_BUFFER_TYPE_INDEX) using the topology ID as the buffer slot. like, set the count first, then go do the cute stuff. the way that sequencing is non-negotiable fr fr ✨

🔥 EXIT STATUS 🔥

if something goes wrong, an error code is set that can be queried using rtcGetDeviceError. so like, check that. don't just sit there wondering why nothing's working. 💀

mwah 💋 that's the page. this one came to you from the Embree Ray Tracing Kernels 3 manual set, and yeah the footer got squished down to rtcSetGeo...eStepCount(3) like a text message that got cut off mid-sentence 😭 but the vibe is intact and the facts are all here. go forth and topology, bestie 🌈💜
