oelin / l-system

Simple implementation of L-systems in Python.

L-system

Lindenmayer Systems, or L-systems, are a mathematical formalism introduced by biologist Aristid Lindenmayer in 1968 to describe the growth processes of plant development. They have since found applications in computer graphics, art, and linguistics. This repository provides a simple implementation in Python.

Usage

Define an L-system. The example below represents a binary tree.

system = LSystem({
    'X': 'XX',
    'Y': 'X[-Y][+Y]',
})

Grow the system for some number of steps.

system.grow('Y', steps=3)  # Returns 'XX[-X[-Y][+Y]][+X[-Y][+Y]]'
