gleSetNumSides(3GLE)

✨ gleSetNumSides — bestie edition ✨

ok so this is gleSetNumSides and gleGetNumSides, from the GLE manual (section 3GLE), and they're literally just here to let you peek at and/or change how round your cylinders are. 💅

---

🎀 NAME 🎀

gleSetNumSides, gleGetNumSides — query and set the cylinder roundness. that's it, that's the whole job. roundness management. iconic.

---

🦋 SYNTAX 🦋

void gleSetNumSides (int nslices);
int gleGetNumSides (void);

---

🌸 ARGUMENTS 🌸

• nslices — a positive integer number of slices. like, a real count of sides. no negatives, no zero, bestie, we're being serious.

---

💖 DESCRIPTION 💖

okok so. query and set the GLE cylinder and cone roundness. that's the vibe.

when GLE draws a cylinder or a cone, it approximates the circular cross-section with a polygon — and that polygon has 20 sides by default. not a real circle. a fake circle. a circle that's doing its best. 🫶

these subroutines let you change the default number of sides in this cross-section. so if 20 isn't the moment for you, you can say something.

here's the tea though:

• a smaller number of sides can typically be drawn much faster — at the loss of some visual accuracy. speed vs. pretty. the eternal struggle. 😭
• increasing the number of sides to more than 20 will typically have no noticeable visual effect. so like... you can, but why. it's giving diminishing returns. 💀

---

💀 BUGS 💀

multiple threads using GLE share a single global number of sides. so if one thread changes it, everybody's changing it. chaos. no cap.

(although this should be easily fixable because GLE does use a centralized graphics context — so like, the fix is right there, someone just has to do it 🙈)
