Cool stuff, now add some physics to those branches :)

I did some experimenting on that direction, but stopped at this weird thing. The way I'm doing it would be too slow with more than one tree

Cool. Is this made with L-systems?

[–] fbmac@lemmy.fbmac.net 2 points 2 years ago (1 children)

It is recursively changing the angle at random and shrinking the size. I dunno if that would count as a L-system, the wikipedia article for L-system has too much math that I don't understand

Track down a copy of "The Algorithmic Beauty of Plants". The last time I looked, it was available as a free PDF, too. I think it's a great introduction to L-systems.

I got it when it was first released and spent way too much time poring over it and generating imagery on my decrepit old computers.

I've never looked at plants the same since.

Thanks, I found this book and a lot of papers about it on this site: http://algorithmicbotany.org/

Nice! That Vlab software looks very interesting. Way back when, I built some primitive tools to help me play with L-systems, but I'd never have dreamed of taking it that far.

Have fun!
