💅 extrusion(6) — the XScreenSaver manual, but make it make sense

okay so bestie, welcome to extrusion(6) 💖 this is the XScreenSaver manual page for extrusion, and honestly? she's an icon. let's get into it.

✨ NAME ✨

extrusion — literally just various rotating extruded shapes. that's the whole vibe. 🌀

🫶 SYNOPSIS 🫶

extrusion [--display host:display.screen] [--visual visual] [--window]
[--root] [--window-id number] [--delay number] [--name which] [--no-light]
[--wireframe] [--fps]

no cap, that's the whole invocation. now let's break it down 👑

🦋 DESCRIPTION 🦋

so what does it do? it draws various rotating extruded shapes that twist around, lengthen, and turn inside out. that's it. that's the tea. ☕✨ like, shapes that are out here living their best main-character lives — twisting, stretching, going full inside-out. it's giving geometry but make it fashion. 💅

🎀 OPTIONS 🎀

okay this is the part where we go through every single flag because we are thorough and we do not skip. not me being a completionist. 🙈

  • --visual visual — pick which visual to use. legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. hex is valid, bestie, don't be scared. 🔥
  • --window — draw on a newly-created window. this one is the default, so if you do nothing, this is what you get. 👑
  • --root — draw on the root window instead. big "I live on your desktop wallpaper" energy.
  • --window-id number — draw on the specified window. you gotta tell her which window, obviously. 🪟
  • --delay number — per-frame delay, in microseconds. default: 10000 (0.01 seconds.). yes microseconds, yes tiny, yes that's on purpose. ⏱️
  • --name which — which object to draw. choices are: helix2, helix3, helix4, joinoffset, screw, taper, and twistoid. that's seven (7) whole shapes and every one of them ate. 🍓
  • --light | --no-light — whether to light the scene, or use flat coloring. lit or flat, pick your fighter. 💡
  • --bitmap file — the texture map to use. 🖼️
  • --wireframe — render in wireframe instead of solid. skele-mode. lowkey gorgeous. 💀
  • --fps — display the current frame rate, CPU load, and polygon count. three numbers, one flag, we love a multitasker. 📊

🌈 ENVIRONMENT 🌈

the environment variables she reads, in order, no skips:

  • DISPLAY — to get the default host and display number.
  • XENVIRONMENT — to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. (yes that's the whole sentence, yes it's a lot, yes it matters.) 🧚
  • XSCREENSAVER_WINDOW — the window ID to use with --root.
