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

The aim of the project is to create a lightweight 3D engine with a very low level of complexity — in other words, for dummies. 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.

	<script src="js/Three.js"></script>

This code creates a camera, then creates a scene, adds a cube on it, creates a &lt;canvas&gt; renderer and adds its viewport in the document.body element.

	<script>

		var camera, scene, renderer,
		geometry, material, mesh;

		init();
		animate();

		function init() {

			camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 1, 10000 );
			camera.position.z = 1000;

			scene = new THREE.Scene();

			geometry = new THREE.CubeGeometry( 200, 200, 200 );
			material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );

			mesh = new THREE.Mesh( geometry, material );
			scene.add( mesh );

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

			document.body.appendChild( renderer.domElement );

		}

		function animate() {

			// Include examples/js/RequestAnimationFrame.js for cross-browser compatibility.
			requestAnimationFrame( animate );
			render();

		}

		function render() {

			mesh.rotation.x += 0.01;
			mesh.rotation.y += 0.02;

			renderer.render( scene, camera );

		}

	</script>
