IFS
Colouring Method


This HTML page describes the different parameters you can find in the mde - IFS colouring method. For further explanations or just suggestions, you may contact me at mdessur@hotmail.com.

I would also mention that English is not my first language. So, I would appreciate comments on how to better this text from that point of view. Thanks.


The colouring method

There are two versions for IFS. One is in the mde folder and is more in French. The other one is in English and you'll find it in the mde-eng folder.

This method uses some IFS formulas that I have taken in "Fractal programming in C", by Roger Stevens, M&T Publishing, 1989, ISBN 1-55851-038-9, p.394 to 397. These are formulas to obtain Sierpinsky triangle, fern leaves, fractal trees and Cantor trees by using the Chaos algorithm (there are some other algorithms related to IFS).

As you will remark by using the colouring method, you will get none of the four figures. I did not have any intent of making IFS in UF by converting the programs of this book to UF code. My intent was more to see 'what if?'.

Here are the parameters for this colouring method. For those related to the Chaos, take a look there. It also uses the  Masking Parameters Toolbox.

Colouring Mode The goal of this parameter is using some properties of the formula for coloration.
