plants

Program to create visualizations of plants and other fractals in Python using l-systems

Explenation

For now it's only a simple program with some operations and a simple parser for the turtle in python. I'm looking into how to make it compatible with some sort of programming language or JSON/toml like config file. My preference now is for creating a simple programming language for defining rewriting rules, and constants like the angle or the axiom.

Progress

I need to do 2 big things;

Add parametric grammars, this is somewhat difficult but leads to beatiful pay offs
3D support, for stuff like trees in 3D space What I need to add for creating a programing language for defining the rules;
Defining the grammar of the language
A lexer for lexing the input of the file
A parser for parsing the tokenized output of the lexer
An evaluator to evaluate the parsed content.
Map the output of the evaluator to the rewriting system of the l-system

Dependencies

Python3.x
Tkinter

Running the script

For now it's easy to run this script. The following steps are what you need to follow.

Clone the repo

Clone deze repo in de top directory van XAMPP dat is htdocs

$ git clone https://github.com/Thom2503/plants.git

Run the script

Go to the cloned folder.

$ cd plants

Run the rec.py script:

$ python3 rec.py

Editing the rules for creating figures

This is the process to alter the rules for the visualization of the figure. There are different global variables that you can edit, except for OPS. These are RULES, ITERATIONS, ANGLE. Changing ITERATIONS will tell how many times the rewriting is done. Changing ANGLE changes the degrees at which the turtle turns. RULES is where the rules are made;

    'X': 'F+[[X]-X]-F[-FX]+X',
    'F': 'FF',
    '+': '+',
    '-': '-',
    '[': '[',
    ']': ']',

These rules with the starting input being X will output a fractal tree if you call moveTurtle(createString("X", ITERATIONS)).
