Rajaa Thanks for sharing this...

Wow, this is so helpful.  Thank you so much!!

Hi Nicole,

I posted another example under the fractal tree (above) with dynamic angle control hooked to a slider.  That should help.

I'm so glad to see that this post is still active!

I've been experimenting with the fractal plant file, but as a complete Grasshopper n00b I cannot for the life of me figure out how to change the rotation angles for + and -.  I notice that the panels "Rotate 25" etc. aren't connected to anything, and that there aren't any 25s in the code, so where could it be?

I'm sure it's totally obvious, but if anybody could help I'd be so thankful! ^^

I've been trying to tell the script to start the branching at a point, but I've been failing miserably. Could you possibly post a script that I could follow? Thank you

Hi Nicholas,
I am sure there is probably a way to write an L-System that produces result similar to the one in the photo.  I just have not written one and my guess it will take some experimenting to get a new variation of an L-System.  Sorry I do not have something offhand to pass.

Sorry I would like to change my question. Similar to this photo I want the L-system to create a layering effect that begins to create a density. Also is there a way to have the L-System to branch out in multiple directions like in the photo above? Sorry for the loaded question hope it's not too much to ask. Thank You

Not sure what you need.  Can you show an image or an example of what you want to get?

I was wondering if there's a way to use the fractal plants logic bt instead have the branches be curves instead of orth0gonal lines.

in 7.0030 version of grasshopper this def throws a critical error that causes the grasshopper canvas to go red. any chance you can update for 7.0030
