Thanks...yes, I'll post the def soon!

great work. a great organic effect. I like that you used tetrahedron based approach, with a limiting function. to my non-botanist eye, looks very much like bristlecone pine found high altitude in colorado or along the pacific coast. thanks for posting, and for outlining the logic sequence, at some point if you would share the file, highly appreciated.

thanks!'s all really basic. just triangles as growth tips defining planes, which are offset, with each iteration being a bit smaller than the last, and then mesh quads formed along each shared edge of the trianges...the branching makes a tetrahedron from each triangular tip. the stochastic part is where the three available branch tips at each growth iteration get reduced...first, the two that are closest to a guide curve are retained, and then the remaining branches do a test where they look to see if they'll clash with any mesh that exists from a previous iteration of the loop...if they do, they cap themselves. Then weaverbird for the subdivision...I'll post the def when the next version of anenome comes out...:)

nice! how did you do the meshing? with exoskeleton?

Wow that's great! Any video tutorials available for it?
