Anyone here with some experiance in fractals and recursive functions ? Its melting my brain a little 😅

Actually, would you recome d using global variables in recursive functions ? Right now it was just 2 functions interwoven(in the picture case about 2200 times on 7 levels deep) but next one might have like 6 functions so it seems like lot of variables to keep track and send around so if its global it might simplify idk

Actually, no, I wouldn't recommend it. Recursion in python is not a good idea in itself, I would recommend avoiding it by resorting to loops if possible. As for variables, it is better to keep them as arguments to functions than as global constants, such code will be much easier to maintain and reuse.

End goal would be to implement it to blender as geometry node and generate trees or sth. But i will need to learn geometry nodes first for that haha

I started to write code, but realized that what I want to write has already written :) Check this out: https://github.com/miaisakovic/l-system-drawings/blob/main/l_system.py Basically, no matter how complex your L-system is, you don't need to complicate the code that builds it, just parameterize it with other rules.

Note, there is no recursion in the implementation.

You couls peobably do the stacking like done for saving positions and i will look into that but yeah when i looked at it all i thought maybe i should try recursive functions and i never used them so it was kinda also part of an exploration and learning

3rd thing taht i run into when trying to do it "instructions" method was that firther down the iteration you go, length of forward movement gets smaller same with width and then keepeng track of that in prewritten instructions would be quite complicated.You cant just copy paste rules but need to keep updating variable

Second problem is that it is actually 3d problem that seems to be then projected to 2d but im not sure about that. In equation +- rotate around x axis whole /\ rotates around y axis

Yeah so thats the first method i already did where you generate instructions first and then just plot it. Turtle library makes lot of the steps also much easier but idk how would it work in blender when i need to specify object dimensions and so on.
