Types of Fractals
IFS FractalsWHAT ARE THEY?
To make an IFS fractal, you start with a figure and using several geometric transformations transform it into several smaller figures. By doing the same to the resulting figures and continuing infinitely you can get a fractal (see IFS iteration for a detailed description). Many fractals formed by this kind of iteration can also be formed by other methods, such as l-systems. However, for many other fractals, which we will call IFS fractals, this is the only method. What is characteristic of IFS fractals is very clear self-similarity:
Because of the great variety of IFS fractals, they can be used in many different applications, depending on what they resemble. One of the main applications is creating very realistic plant models, using IFS fractals such as the famous Barnsley Fern.

Function Systems Playground
A great website about iterated function systems. It has a very beautiful gallery, and even CGI programs that allow to create your own IFS fractals.
