You can write rules in the blender text editor, just rename the text using the prefix “LSYS”
The grammar is written in form of a python dictionary, you can write a fractal object to a text block to get a template or store a setting.
If you find the way to convert this on a kind of sculpting brush, (for example apliying the script to the poligons selected by the brush with graduation of stregth) it would be a very interesting addon that you could sell, there is not a lot of things on bio inspired modelling on todays 3D soft.
I LOVE L-Systems! Haven’t played with them in years, really going to have fun with this. A long time ago I tried to implement one inside of POV-Ray, which sort of worked. Kudos for bringing more organic awesomeness to Blender!
Thank you and good to know! I need some feedbacks about improvements!
Initially I tried to do somethink like that into modo, but I lacked the skin modifier!
The main concept is to get a fast way to generate Lsystem extrusion without break the direct modelling workflow, so I would keep it a modelling operator…
Since the overwriting rules are easily reusable I would try to get a preset database shared also with the animation node Lsystem generator, this is easy to obtain using text data to define axiom and rules…
So I’m going to add a load text rules button once I figured out how to do.
Yes, I think I ll add two other option:
1 translate the extrusion in a lsystem animation node setup ( and uniform the rules sintax accordingly)
2 a sort of brush to deploy the extrusion on the surface with auto remesh ( in a dyntopo sculting workflow)
Do you have a few example more for to fill in AXIOM and RULES.
I wrote an article about your addon and want to give a few more examples to get the users started. I copied already the two examples in the screenshot.
I find this a very interesting addon and thought about it quite often.
Do you have plans to make a few more examples, or do you have plans for further development?
I think it might be a bit hard for users to get through the syntax of L-system and some examples will help.
I believe we owe gratitude to the op for his creation by looking at all the established material available for l-systems. Above is a start. If you put a search in for l-system and your software of choice, I’m sure you will find something.
Users get to do some of that lifting even if its called learning.
