rtcSetGeo...ationRate(3)

💖 rtcSetGeometryTessellationRate — bestie edition 💖

okay so welcome to rtcSetGeometryTessellationRate(3) from the Embree Ray Tracing Kernels 4 manual, part of the Embree Ray Tracing Kernels gang 🫶. this one's short, sweet, and honestly? a little iconic. let's get into it 💅

---

✨ NAME ✨

rtcSetGeometryTessellationRate — sets the tessellation rate of the geometry. that's it. that's the whole job. she does one thing and she eats 🔥

---

✨ SYNOPSIS ✨

#include <embree4/rtcore.h>

void rtcSetGeometryTessellationRate(
  RTCGeometry geometry,
  float tessellationRate
);

like, look at her. two arguments. no drama. no cap 🎀

---

✨ DESCRIPTION ✨

okay so rtcSetGeometryTessellationRate sets the tessellation rate (that's the tessellationRate argument, bestie 🌸) for the geometry you hand it (the geometry argument, obviously 💁).

BUT. and this is the important part, don't skip this — the tessellation rate can only be set for flat curves and subdivision geometries. that's the vibe check. if you try to set it on something else, that's not the move, and the manual is very clear about it. lowkey a limited-edition situation ✨

so what does it actually mean, you ask? it depends on which one you're on:

• For curves — the tessellation rate specifies the number of ray-facing quads per curve segment. so like, more rate = more quads per segment, facing the rays. 🌈
• For subdivision surfaces — the tessellation rate specifies the number of quads along each edge. yeah. along each edge. that's the whole thing. 💜

no guessing, no extras, that's literally what it does. periodt. 💅

---

✨ EXIT STATUS ✨

if it fails, an error code gets set, and you can go query it with rtcGetDeviceError. so like, if things go sideways, that's where you check. on failure — that's the condition, bestie. go look it up. 😭

no, she does not return the error directly. she sets it. you go ask rtcGetDeviceError about it. iykyk 🧚

✨ SEE ALSO ✨

• [RTC_GEOMETRY_TYPE_CURVE] — the curve girlies 🦋
• [RTC_GEOMETRY_TYPE_SUBDIVISION] — the subdivision girlies 🌸

and that's the whole page, bestie!! this one came straight out of the Embree Ray Tracing Kernels 4 manual, with the header up top and the footer down bottom reading rtcSetGeo...ationRate(3) 💀 (yes they truncated her name in the header, we respect the truncation, it's a whole aesthetic). go forth, set your tessellation rates responsibly, and remember: flat curves and subdivision geometries only. mwah. 💖🎀✨👑
