Demos

Did you find a cool use for normalmap.js? Let me know!

Example

var lights = normalmap({
    canvas: canvas,
    normalMap: normalMap,
    baseColor: [0.5, 0.4, 0.5]
});

lights.clear();

var position = normalMap.vec3(0.5, 0.5, 1.0); // dead center
var color = normalMap.vec3(1.0, 1.0, 1.0); // bright white
lights.addPointLight(position, color);

Installation

With NPM:

$ npm install normalmap

var normalmap = require('normalmap');

With Bower: $ bower install normalmap

Or just download the latest zip file form the releases page.

Note that normalmap.js won't work with file:// urls. You will need to serve images from a webserver. See Richard Daveys phaser introduction for an explanations for this.

Browser Support

Normalmap.js should work in all browsers that supports WebGL.
