Fract-ol

real-time interactive fractal zoomer

Fract-ol shows you depths of famous fractals - Mandelbrot set, Julia set, Newton pool set in real time. You can zoom into the fractal almost infinitely.

Features

• Linux and OSX support
• Mandelbrot set fractal
• Julia set fractal
• Newton pool fractal
• moving and zooming by keyboard and mouse
• select location and parameters of fractal
• making screenshots in .bmp format

Keyboard shortcuts

• zoom into mouse position: mousewheel
• zoom into center of screen: + (or =) and - buttons
• moving position by numpad arrows and with w a s d buttons
• upscaling and downscaling render precision: up and down arrow keys
• changing color palettes: left ans right arrow keys
• changing set parameters: shift + w a s d buttons (only for julia set)
• making screenshot: p
• print information about position and set parameters: i
• exit by pressing x key

Dependencies

you will need these packages: make gcc clang and GUIlib window library (https://github.com/tlucanti/GUIlib)

Installation

1. put GUIlib repo into parent directory to get this structure:

   ..
   ├─ Fract-ol
   └─ GUIlib
   

2. build GUIlib library following its README
3. set enviroment variable $GUILIB to select GUIlib window frontend
4. build Fract-ol with make

Launching

simply run command

./Fract-ol [set]

where [set] is one of options - mandelbrot or m, julia or j, newton or pool or n

You can get information about launch options with --help option

./Fract-ol --help

Examples

Example of Mandelbrot from set from image above:

./Fract-ol m -R1920+1080 -c-0.743643-0.131826i -w2e-5 -d1300

Example of spiral in Julia set

./Fract-ol j -c-3.45e-4i+7.05e-4 -w0.0004 -d6000 -s4 -R1920+1080
