#### Javascript 3D Engine ####
[![Flattr this](http://api.flattr.com/button/button-compact-static-100x17.png)](http://flattr.com/thing/287/three-js)
The aim of this project is to create a lightweight 3D engine with a very low level of abstraction (aka for dummies). Currently the examples are the documentation. Be aware that the API may change from revision to revision breaking backwards compatibility.
The engine can render using <canvas>, <svg> and WebGL.

### Usage ###
Download the [minified library](http://mrdoob.github.com/three.js/build/Three.js) and include it in your html.
This code creates a camera, then creates a scene object, adds a bunch of random particles in it, creates a <canvas> renderer and adds its viewport in the document.body element.
For creating a customised version of the library, including the source files in this order would be a good way to start:
