This is lsystem v1.0. Lsystem is a fractal generator is based on the scheme devised by Aristid Lindenmayer (the L in Lsystem). It is a so-called string-rewriting system, in which an input string is altered according to a set of transform rules. The characters that make up the string, in turn, can represent commands to a "turtle" which will draw the actual fractal. More sophisticated Lsystem incarnations have been used to create very lifelike renderings of plants (see "The Algorithmic Beauty of Plants", written by Prusinkiewicz and Lindenmayer, published by Springer Verlag). This is a fairly noddy implementation I knocked up based on a version I had on my Atari ST. Have fun with it. It's only been tested on BSD4.2 (Ultrix) but it should go on virtually anything (with possible minor hacking). To install, customize the Makefile at the top and type `make install'. Or just `make' first, if you want to test it. zondo@hunting2.demon.co.uk
