A library for basic 2D affine transformations; will likely add other little items


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


npm install -g geom2d

Usage (CoffeeScript example)

{affine, vector, polygon} = 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   0.5, 0.25
# 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

geom2d is written in an improved version of CoffeeScript called "IcedCoffeeScript".
