L-Systems.JS
A complete, 3D L-Systems implementation in JavaScript. Generates trees by production rules and draws by converting to cartesian coordinates.
Usage
var lsys = new LSystem('F', { 'F' : 'F-F+FF' }).iterate(2);
var tree = lsys.print();
console.log(tree); // F-F+FF-F-F+FF+F-F+FFF-F+FF
var coords = lsys.draw(Math.PI / 2); // draw tree with alpha as 90 degrees
console.log(coords); // [[0,0,0], [0,1,0], [1,1,0], ...Definition
An L-system is a formal grammar defined as an initial axiom string, and a set
of production rules. In the aforementioned example, F is the initial axiom,
and only one production rule exists: F -> F-F+FF. The grammar alphabet is
assumed to be all characters with a production rule mapping.
Syntax
F: draw and move one unit vector forward+/-: turn right / left&/^: pitch up / down</>: roll right / left|: reverse vector direction[/]: push / pop current tree state
