An Iterated Function System in Python

This is a fork of James Tauber's initial work.

The tone-mapped image handling comes from Minilight.

NOTE: I strongly recommend using PyPy to run this (it runs about 40x faster)

Running

Just run

python pyifs.py [configuration file]

Configuration

The iterated function system is customizable by using a json configure file (example).

Writing New Transforms

A new subclass of Transform should randomize its parameters in __init__ then implement a transform method that takes two args (the x, y of the point) and returns a new x, y.

To-do

let evaluation of iterated function system be multithreaded
Check on why fern is not centered
Allow customization of image output (background, color schemes)
Make an easier input method? graphical?
add deterministic mode and allow for viewing of iterated steps
