Hello!

I've been digging into the L-system help page and various books about l-systems but I can't get few things working.
skipping all the main problem I jump directly into the straight question:
does anyone has the rules to get the famous Barnsley Fern with L-system SOP?
specifically I'd need this one, the very first one shown here:
http://www.home.aone.net.au/~byzantium/ferns/f0.gif

I tried with the preset "plant D" but that's not exactly the same (or I'm unable to get that exact shape) ...

any help would be very welcome! thanks Smile

As it looks 'Barnsley Fern' ain't a L-System but a IFS.
Same same but different?

However: www.mathworks.com/moler/exm/chapters/fern.pdf
Quote:
The programs fern and finitefern in the exm toolbox produce the Fractal Fern described by Michael Barnsley in Fractals Everywhere [?]. They generate and plot a potentially infinite sequence of random, but carefully choreographed, points in the plane.

You can probably more easily do the same with a Foreach SOP that runs through the probabilities inside a VOP SOP these days.
