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:

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

:roll: no idea anyone?

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

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.

I did this for the (only) houdini hacker contest by using particles:

thanks guys, hmm … well I think I'll work around it somehow.
took a look at your file Ed and I found it very interesting indeed thanks for sharing.

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