A Julia/Mandelbrot Fractal generator written in Java/Swing.

This is just a weekend / Hobby project of me. At the moment the code and output is in a very early stage, let's call it "0.1-alpha", if already. Give me some time :-)

This project does not need you to understand the Maths behind it. It is just to SHOW you the beauty of math.

Main class: ch.alexi.fractgen.Main

Run: "java -Xmx512M -jar JFractGen.jar"

Today's already implemented features

  • Fractal settings presets for 'nice' mandelbrot/julia locations
  • color palette presets
  • define user-presets in json config file (<user.home>/.jfractcalc/presets.json)
  • uses chosable nr of Workers, for using multiple CPUs for calculating
  • dive deeper by click/rubberband zoom, zoom out
  • drag-move the fractal viewport
  • smooth colors / hard edges
  • history
  • dynamic color palette change (without re-calc)
  • multiply color palette
  • PNG export
  • presets defined as JSON data in properties file
  • JSON export/import of presets
  • Transparency support in color schemes

Planned / future features

  • create own color palettes
  • graphic bulk export/conversion/downsampling
  • preferences:
    • nr of workers / CPU dependant
    • max. Nr of history entries
