Fractal Foliage: Executable or Text Version

This is a rather short program. It calls one procedure, which calls a second procedure. But then the second procedure calls the first which calls the second again and so on to a selectable number of levels. Although it's a short program, it could take a very long time to complete if you opt for a lot of levels.

It displays Fractal Ferns, amongst other things. The ferns are displayed using the default settings (just keep pressing Enter when you run the program), but other settings look completely different. The program uses an Iterative Function System or IFS, which is the standard method to produce these kind of fractals.
After the picture has finished, press "d" and the program will progressively work out the Fractal Dimension of the image. Otherwise press the Space-bar to re-RUN, or the Esc or any other key to Exit.
For a more in-depth, but non-mathematically taxing explanation of how the program works, and what Fractal Diemnsion is, I've prepared a Word document: The Quintessence of Fractals

Fractal Trees: Executable or Text Version

A variant on the above, but the output always looks like a tree of some sort. There are rather a lot of parameters, but then that gives almost unlimited variation!

REWRITTEN July 2005: For the .txt version, you'll need to provide your own Tree.jpg and Bground.jpg pictures!!

This is a screen dump of the Fern produced by the default settings. Quite eerily similar to the real thing, I would say.
