L-system iterations
Hi everyone,
here is an abstraction to do L-system iterations as described here: https://en.wikipedia.org/wiki/L-system#Examples_of_L-systems
The rule sets are loaded from text files, and the iterations can also be saved to text files. I'm not sure what the possible uses of this are, and it gets pretty slow as the strings get longer, but it was fun to do.
@weightless Array faster than text has been suggested before, but I do not "know". Just a maybe.
Here is the folder. Obviously will not work without Gem (or zexy or?), but the thinking and some patch representation of it will be there.......recursion.zip
PS.... I also found that the recursions were much faster if not printed to the terminal.

@whale-av Thanks! I will have a look and also try with array and see if there's any difference.
Here is a a small update on the non-propagating one. The head and tail can be set to "loop" in the rules, so for "head" this means that the first element takes its left state from the last element of the previous iteration, and for "tail" it means that the last element takes its right state from the first element of the previous iteration. This already introduces some pretty funky variations.
Simple runner to show the "loop" concept.
@weightless i tried to run the runner algorhytm over the grid from the sierpinski loop algorhytm. a lot more variation, i dont know if it sounds too random. 2lsys.zip
@Jona Very nice!
now both algorhythms have their original pattern. a note is only played if both algorhythms are on one field. different colors from the runner algorhytm represent different midi channels. lsys2b.zip
This is an updated version of the patch that accepts multiple production rules for each predecessor, which are picked randomly every time according to weights. More info and an example inside the patch.
EDIT: updated patch
@Jona This is an excellent idea to combine two patterns. Great stuff. Here is a variation of the sierpinski in place of the runner.
@weightless good idea to take the sierpinski 2 times. i modulated the reset of the iterations differently and use different sounds for different colors (i need to clean up the patch when i have time...): 2lsysd.zip
Oops! Looks like something went wrong!
