Simple 2D L-System Python Implmentation

About:

• I always wanted to implment an L-System, so I did.
• To learn more about L-Systems HERE
• Originally this project was a terminal only program, but though tkinter, it evolved to a GUI & terminal program.
• This project use to be in the algorithm-challenges repo, which has been deprecated until further notice. Due to this, I moved this project to this new repo.

Content:

• This project consists of the following files:
  • draw.py : class with function which does all the L-System drawing using turtle.
  • pfuncs.py : class with functions used to save/load pickle files with L-System saves. It also contains functions for getting the current pwd and creating a list of every file path to a pickle file in the project folder.
  • main.py : main python script for this project. Here the GUI is setup and ran as well as everything else. The main.py script depends on draw.py and puncs.py.
• For this project, there are two other directories:
  • tools : contains useful scripts as well as some random files and some backup files
  • saves : contains all the L-System saves I saved so far
• In tools/, there is a python script called eps_to_png.py. This is a script that can convert an inputed .eps file to a .png file.
  • This script works most of the time, but fails sometimes. So I did not want to include it in the final code.

Tested On:

• Operating Systems:
  • MacOS Catalina (10.15.7)
  • Ubuntu 20.04
• Software:
  • Python3 3.8.13

Requriements:

• Python3
  • Built-In Pkgs:
    • tkinter
    • turtle
    • subprocess
    • os

How To Use:

• Run main.py script to run everything, with the following command (run this once and after you understand the warning message, then start running this command with the -nw option):

   python3 main.py
  

• Run the main.py script without the initial warning message everytime:

   python3 main.py -nw
  

• To convert an eps file to a png, you can use the eps_to_png.py python script by running a command like this:

   python3 eps_to_png.py example.eps example.png
  

Future Plans:

• This code is not perfect and is limited to 2D only. So in the feature I would like to implment this code for 3D L-Systems. I might need to use either Pygame or Unity, I will most liky use Unity for a 3D implmentation of this.
