💥 crumbler — voronoi divisions of a sphere 💥

ok so bestie, welcome to crumbler(6), one of the little gems from the XScreenSaver manual (yes that whole legendary screensaver collection, ilysm). it's a screensaver module, it does exactly one thing, and it does it beautifully: it takes a ball and shatters it into voronoi chunks. no cap. let's get into it 🫶

✨ SYNOPSIS ✨

crumbler [--display host:display.screen] [--visual visual] [--window]
[--root] [--window-id number] [--delay number] [--speed number]
[--density number] [--fracture number] [--no-wander] [--no-spin]
[--wireframe] [--fps]

like, that's the whole invocation. short and sweet, the way we like it 💅

🌸 DESCRIPTION 🌸

okay so here's the vibe: it randomly subdivides a ball into voronoi chunks, and then — and this is the part that sends me — it goes ahead and further subdivides one of the remaining pieces. it just keeps cracking the thing open. main character energy for a sphere tbh. 🧚

🎀 OPTIONS 🎀

  • --visual visual — tells it which visual to use. legal values are the name of a visual class, or the id number of a specific visual (decimal or hex, whichever you vibe with).
  • --window — draws on a newly-created window. this is the default, so if you don't say anything this is what you get 😌
  • --root — draws on the root window instead.
  • --window-id number — draws on the specified window. you gotta give it a number, bestie.
  • --delay number — per-frame delay, in microseconds. default is 30000 (that's 0.03 seconds, in case math isn't your era).
  • --speed number — animation speed. 2.0 means twice as fast, 0.5 means half as fast. choose your fighter 🔥
  • --density number — density of the polygons mesh. 2.0 means twice as dense, 0.5 means half. crunchy little polygons, yum 🍓
  • --fracture number — how many times to fracture each object. 0 means random, i.e. let the algorithm surprise you 💀
  • --wander | --no-wander — whether the object should wander around the screen. it's giving lost in the club.
  • --spin | --no-spin — whether the object should spin. iconic rotation, honestly.
  • --wireframe | --no-wireframe — render in wireframe instead of solid. skeleton mode, very chic.
  • --fps | --no-fps — whether to show a frames-per-second display at the bottom of the screen. numbers go brrr ⭐

🦋 ENVIRONMENT 🦋

env vars, aka the invisible little helpers 🌈

  • 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.
  • XSCREENSAVER_WINDOW — the window ID to use with --root.
