#### Javascript 3D Engine ####

[![Flattr this](http://api.flattr.com/button/button-compact-static-100x17.png)](http://flattr.com/thing/287/three-js)

Currently the engine only supports particles and triangles/quads with flat colors. The aim is to keep the code as simple and modular as possible.

At the moment the engine can render using <canvas> and <svg>. WebGL rendering would come at a later stage but feel free to fork the project and have a go.

Although this allows 3D for iPhoneOS and Android platforms the performance on these devices is not too good.

### How to use ###

The library needs to be included first thing.

	<script type="text/javascript" src="js/three.js"></script>

Now we have access to the engine classes and methods.

This code creates a camera, then creates a scene object, adds a bunch of random particles to the scene, creates a &lt;canvas&gt; renderer and adds its viewport the document.body element.

	<script type="text/javascript">

		var camera, scene, renderer;

		init();
		setInterval(loop, 1000 / 60);

		function init() {
		
			camera = new THREE.Camera(0, 0, 1000);

			scene = new THREE.Scene();
	
			renderer = new THREE.CanvasRenderer();
			renderer.setSize(window.innerWidth, window.innerHeight);

			for (var i = 0; i < 1000; i++) {
			
				var particle = new THREE.Particle( new THREE.ColorFillMaterial(Math.random() * 0x808008 + 0x808080, 1) );
				particle.size = Math.random() * 10 + 5;
				particle.position.x = Math.random() * 2000 - 1000;
				particle.position.y = Math.random() * 2000 - 1000;
				particle.position.z = Math.random() * 2000 - 1000;
				particle.updateMatrix();
				scene.add( particle );
				
			}

			document.body.appendChild(renderer.domElement);
			
		}

		function loop() {
		
			renderer.render(scene, camera);
			
		}

	</script>

If you are interested on messing with the actual library, instead of importing the three.js compressed file, you can include the original files in this order:
