Domain Coloring Movies and X11 Display

Overview

This program generates a series of pictures which can be run through a program, such as ffmpeg, to produce a domain coloring movie. It also creates an X11 display for viewing it as you go.

The program was adapted from this code found on Wikipedia and with much help from Chris Wellons to actually get it to compile.

Download

The program can be run without any command line arguments. It requires a directory named data be present.

domainColoring.tar.gz: Tarball of everything
domainColoring.c: Source code
makefile: Makefile to compile the program
ffmpegScript: Script to make a movie after running domainColoring

Making Graphs

Being lazy I didn't include the ability to pass in parameters. Everything is defined in very simple to read constants at the top of domainColoring.c, and the function that defines the graph is called fun. Obviously every change requires a recompile. I know of no 'eval' type functionality in C, so no matter what the source always has to be changed when making a new function.

Movies Of Execution

Variables:

s: Complex input
t: Time/Frame of Animation

Conclusion

This works well, and is much faster than the Online Python version. This biggest drawback is needing to recompile for little changes to the algorithm used.

I really like the first two animations, especially the periodicity of the second
one. And I like that you made the link images equations.
