julia(6x)

okay so bestie, welcome to julia(6x) from the XScreenSaver manual ✨💅 This one is a whole little fractal queen, and she is literally spinning and animating julia-set fractals. No cap.

🎀 NAME 🎀

julia — draws spinning, animating julia-set fractals. That’s the whole vibe check: spinning, animating, julia-set fractals, periodt. 🌀💖

✨ SYNOPSIS ✨

Run her like this, bestie:

julia [--display host:display.screen] [--foreground color] [--background
       color] [--window] [--root] [--window-id number][--mono] [--install]
       [--visual visual] [--ncolors integer] [--delay microseconds] [--cycles
       integer] [--count integer]

       [--fps]

🦋 DESCRIPTION 🦋

Okay so julia draws spinning, animating julia-set fractals. Main character energy fr fr. 🌈

It uses ifs {w0 = sqrt(x-c), w1 = -sqrt(x-c)} with random iteration to plot the julia set, and sinusoidially varied parameters for the set, and plots parameters with a circle. Yes bestie, that’s the exact math tea ☕✨.

One thing to note — and this is important, don’t skip it — count is the depth of the search tree, so the number of points computed is (2^count)-1. The page says “I use 8 or 9 on a dx266 and it looks okay.” Noted, iconic dx266 behavior 👑. The sinusoidal variation of the parameter might not be as interesting as it could, but it still gives an idea of the effect of the parameter. That’s the honest review from the manual, ngl. 💜

Dragging the mouse in the window uses the mouse’s position as the control point for the generation of ths set. (Yes, “ths” — the original said it, not me 😭🫶.)

💅 OPTIONS 💅

julia accepts the following options:

• --window — Draw on a newly-created window. This is the default. 🪟✨
• --root — Draw on the root window. 🌈
• --window-id number — Draw on the specified window. 🎯
• --mono — If on a color display, pretend we’re on a monochrome display. 🖤
• --install — Install a private colormap for the window. 🎨
• --visual visual — Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. 👀
• --ncolors integer — How many colors should be used (if possible). Default 200. The colors used cycle through the hue, making N stops around the color wheel. 🌈💖
• --cycles integer — (the original page leaves this one blank, bestie 😭)
• --count integer — (same here — no description given in the OPTIONS list 🫶)
• --fps — Display the current frame rate and CPU load. 🔥

Also, the SYNOPSIS up top shows --display host:display.screen, --foreground color, --background color, and --delay microseconds — they’re in the synopsis, but the page’s OPTIONS section doesn’t add descriptions for them. Keep that in mind, iykyk. 💜

🌸 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. 🪟

okay bye bestie, this page comes from X Version 11 — 6.09 (07-Jun-2024) — and it’s the julia(6x) page, so go make some spinning fractal art and slay 💅🌈💖
