gtscheck(1)

✨ gtscheck — the vibe check your mesh has been BEGGING for ✨

okay bestie, so this is a page from the GNU Triangulated Surface utils manual (gtscheck(1), section 1, the classics 💅). sit down, grab a strawberry 🍓, and let's talk about whether your surface is actually serving closed, orientable, non-self-intersecting manifold realness — or whether it's giving messy 🫶

🌸 NAME 🌸

gtscheck — checks that a surface defines a closed, orientable non self-intersecting manifold.

like. that's the whole job. it's the friend who looks at your outfit and tells you the truth. no cap.

🎀 SYNOPSIS 🎀

gtscheck [OPTION] < FILE

notice the < FILE bestie — this one reads from standard input, it does not take a filename argument. it's not gonna chase your file down. you gotta hand it over. 💅

🦋 DESCRIPTION 🦋

This manual page documents briefly the gtscheck command.

(translation: this page is the quick rundown, not the whole novel. it tells you what you need, periodt.)

✨ OPTIONS ✨

These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-`). A summary of options is included below.

• -v, --verbose — Print statistics about the surface. 👑 the receipts! the numbers! the tea!
• -h, --help — Display the help and exit. 🫶 the "ma'am, just tell me what to do" button.

💀 EXIT STATUS 💀

The return status reflects the error encountered:

• 0 — none 🌈 (you ate. nothing went wrong.)
• 1 — the input file is not a valid GTS file 😭
• 2 — the surface is not an orientable manifold 🙈
• 3 — the surface is an orientable manifold but is self-intersecting 💀

fr fr, read those carefully — 2 and 3 are different problems. orientability is one thing, self-intersection is a whole other thing. the exit code is telling you which one you've got. don't conflate them, bestie.

shoutout to them, iconic behaviour honestly 🎀

and that's the whole page! 🦋 this beauty comes to you from the GNU Triangulated Surface utils, dated June 2, 2008 — vintage, but she still hits. go check that manifold, bestie. i believe in you. ✨💜
