✨ NAME ✨

interference — decaying sinusoidal waves 🌀

🌸 SYNOPSIS 🌸

interference [--display host:display.screen] [--visual visual]
[--window] [--root] [--window-id number] [--count number] [--gridsize
number] [--delay number] [--speed number] [--radius number] [--ncolors
number] [--color-shift number] [--hue number] [--no-db] [--fps]

🦋 DESCRIPTION 🦋

So there's this whole genre of hacks that just vibe out with color fields, right? This is another one of those — a color-field hack, periodt. But the way it works is genuinely iconic: it computes decaying sinusoidal waves and then lets them interfere with each other as their origins move around. that's it. that's the whole bit. and it's gorgeous, ngl 💖

🎀 OPTIONS 🎀

• --visual visual — picks which visual to use, bestie. legal values are either the name of a visual class, or the id number (decimal or hex, both slay) of one specific visual.
• --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. main character energy.
• --window-id number — draws on the exact window you specify. you pick, she draws. 💅
• --count number — Number of Waves. <yellow>0 - 20</yellow>. Default: 3.
• --gridsize number — Magnification. <yellow>1 - 20</yellow>. Default: 2.
• --delay number — Per-frame delay, in microseconds. Default: 30000 (that's 0.03 seconds., yes the manpage really does have a trailing period there, we don't gatekeep punctuation 😭).
• --speed number — Wave Speed. <yellow>1 - 100</yellow>. Default: 30.
• --radius number — Wave Size. <yellow>50 - 1500</yellow>. Default: 800.
• --ncolors number — Number of Colors. Default: 192.
• --color-shift number — Color Contrast. <yellow>0 - 100</yellow>. Default: 60.
• --hue number — Hue of the base color, <yellow>0-360</yellow>, as in HSV space. Default 0, meaning random — so if you don't pick, the universe picks for you ✨
• --db | --no-db — whether to double buffer. that's the whole toggle, no notes.
• --fps — Display the current frame rate and CPU load. little performance check-in, we love to see it 👑

---

🌈 ENVIRONMENT 🌈

• 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.
