# Lindenmayer (LSystems)

This package builds and draws Lindenmayer systems (LSystems). It uses Luxor.jl to draw the graphics.

L-systems were introduced and developed in 1968 by Aristid Lindenmayer, a

Hungarian theoretical biologist and botanist at the University of Utrecht.

Lindenmayer used L-systems to describe the behaviour of plant cells and to model

the growth processes of plant development. L-systems have also been used to

model the morphology of a variety of organisms and can be used to generate

self-similar fractals such as iterated function systems.



```julia

using Lindenmayer

plant  = LSystem(["F" => "F[-F]cF[+F][F]"], "F")

drawLSystem(plant,

    forward              = 6,

    startingpen          = (0, 0.8, 0.3),

    startingx            = 0,

    startingy            = 400,

    startingorientation  = -π/2,

    turn                 = 17,

    iterations           = 6,

    filename             = "plant.png")

```
