Software | Java Fraxion

Fraxion (version 1.3.5) is a multi-threaded fractal exploration application, mainly providing Mandelbrot/Julia-type, Newton/Raphson-type, Magnet-type, and Markus/Lyapunov-type fractals (with arbitrary bifurcation diagrams supported for divergent fractals). It is based on the SMTools GUI framework.

To run the program, download the distribution from above and execute the following command (example for Windows)

  • java -cp %CLASSPATH%;smtools.jar;log4j.jar;jlayer.jar;jna-3.5.1.jar;platform-3.5.1.jar;jhbasic.jar;fraxion.jar org.sm.fraxion.gui.FraxionGUI

Depending on available memory and type of system, you can add the following options before the -cp parameter:

  • java -server -d64 -Xmx8000M -Xms8000M -XX:+UseCompressedOops -XX:+AlwaysPreTouch -XX:+UseLargePages -XX:LargePageSizeInBytes=4m -cp ...

The GUI is multilingual; you can specify a locale as a parameter following the command:

  • ... org.sm.fraxion.gui.FraxionGUI -locale=ukenglish

Below are some screenshots from the program in action (click to enlarge).











        

The following photo was taken at a beach in Alicante, Spain, in August 2014, where I engraved the base formula in the sand (it's over 10 metres in length). I asked for Mandelbrot's autograph during his "Fractal Scaling in Financial Prices" lecture at the KU Leuven (23 March 2004), where he signed my copy of The Beauty of Fractals.
