JFractGen

(c) 2012 Alexander Schenkel, http://www.alexi.ch alex@alexi.ch

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 about let you SEE the beauty of math.

Main class: ch.alexi.fractgen.Main

Run: java -Xmx 512M -jar JFractGen.jar

Or just the starter shell script: sh jfractgen.sh

Today's already implemented features

• Fractal settings presets for 'nice' mandelbrot/julia locations
• color palette presets
• define user-presets in json config file (/.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

Planned / future features

• create own color palettes
• graphic bulk export/conversion/downsampling
• limit max # of history entry, to save memory
