2D Fractal Tree

2D Fractal Tree ================ This creates a two-dimensional tree that can be used to create laser-cut designs. It's possible to create a 3D extrusion of the tree using the following code: ``` linear_extrude(height = 5) { trunk(); } ``` Based on "Procedurally Generated Trees" by steveweber314 on Instructables http://www.instructables.com/id/Procedurally-Generated-Trees/ To use with an OpenSCAD design: ``` use <path/to/this/file/fractal_tree.scad>; ``` Call with: ```javascript trunk(); ``` Parameters: ------------ * size: [real] - Base size for the trunk * depth: [integer 0:1] - Number of recursions (warning: exponentially more operations per increase of depth) * seed: [real>0] - Random seed to base tree on * widthBottom: [real 0:1] - Width of bottom of each segment as a proportion of size * widthTop: [real 0:1] - Width of top of each segment as a proportion of size * joint: [real 0:1] - Size of joint as percentage of size * minGrowth: [real 0.1:1.2] - Minimum amount to grow branch as percentage of previous * maxGrowth: [real 0.1:1.2] - Maximum amount to grow branch as a proportion of previous * leafScale: [real 0.1:1] - Radius of leaf as a percentage of branch size * leaf: [boolean true:false] - True: include leaves, False: skip leaves
