💫 glhanoi — the OpenGL Towers of Hanoi situation

okay so this is a page from the XScreenSaver manual, and bestie, it's about the Towers of Hanoi but make it OpenGL. yes, that classic recursion puzzle, now with ✨rendering✨. let's get into it.

🌸 SYNOPSIS 🌸

[--root] [--window-id number] [--delay number] [--count number] [--poles
number] [--speed number] [--wireframe] [--light] [--texture] [--fog]
[--fps]

that's the whole invocation, no cap. (heads up: --display shows up here in the synopsis, and the options list below is exactly what the page spells out — i'm not gonna make stuff up about it, iykyk.)

🎀 DESCRIPTION 🎀

it's a Towers of Hanoi implementation, and it's in OpenGL. that's literally the whole description. iconic brevity, honestly. 💅

✨ OPTIONS ✨

  • --visual visual — picks which visual you want. legal values are either the name of a visual class, or the id number of a specific visual (decimal or hex, your call 🫶).
  • --window — draws on a brand-new window that just got created. this is the default, so it's giving main character energy by default.
  • --root — draws on the root window instead.
  • --window-id number — draws on the window you point at with that number.
  • --delay number — the per-frame delay, measured in microseconds. default is 30000 (that's 0.03 seconds, for the people keeping score ⏱️).
  • --count number — how many disks. default: 7.
  • --poles number — how many poles. default: random from 3 to disks+1 — so yes, it vibes and picks for you 🎲.
  • --speed number — speed multiplier, and it applies to the smallest disks. default: 1.
  • --trails number — the length of the disk trails, in seconds. default: 2.
  • --wireframe | --no-wireframe — render in wireframe instead of solid. wires only, no chunks.
  • --fog | --no-fog — render in fog. spooky lil atmosphere, optional.
  • --fps — shows you the current frame rate, the CPU load, and the polygon count. numbers go brrr 📊.
  • --light | -no-light — whether the scene is lit. (that second one is written -no-light on the page, one dash, don't come for me, i'm just the messenger 🙈)
  • --texture | --no-texture — render with textures instead of solid.

🦋 ENVIRONMENT 🦋

  • DISPLAY — used to get the default host and display number.
  • XENVIRONMENT — used 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.
