    geom2dpublic

    Explanation

    A very alpha version of a JS Library for doing affine transformations and (coming soon) other simple transformations I need for a bigger project. My first node module. Written in IcedCoffeeScript.

    Browser Use

    <script src="geom2d.js"></script>
    <script>
     var affine  = require('affine');
     var polygon = require('polygon');
     
     var rot_left  = new affine.rotation(  Math.PI / 4);
     var rot_right = new affine.rotation( -Math.PI / 4);
     var go_big    = new affine.scaling (  2,   4);
     var go_small  = new affine.scaling (  0.5, 0.25);
     
     var do_nothing = rot_left.copy();
     do_nothing.rightComposeWith(rot_right);
     do_nothing.rightComposeWith(go_big);
     do_nothing.rightComposeWith(go_small);
     
     var square = polygon.factory.unitSquare();
     
     document.write("<h3>Square before</h3>");
     document.write(JSON.stringify(square));
     
     document.write("<h3>Square after</h3>");
     square.transform(do_nothing);
     document.write(JSON.stringify(square));
    </script> 

    Node Installation

    npm install -g geom2d
    

    Usage (CoffeeScript example)

    {affinepolygon} = require 'geom2d'
     
    rot_left  = new affine.rotation  Math.PI / 4
    rot_right = new affine.rotation -Math.PI / 4
    go_big    = new affine.scaling   2,   4
    go_small  = new affine.scaling   0.50.25
     
    # 4 compositions that should net nothing 
    # -------------------------------------- 
    do_nothing = rot_left.copy()
    do_nothing.rightComposeWith rot_right
    do_nothing.rightComposeWith go_big
    do_nothing.rightComposeWith go_small
     
    square = polygon.factory.unitSquare()
    square.transform do_nothing
     
    console.log square
