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

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

This project is work in progress. Before using it in a project be aware that the syntax may change from revision to revision without being backwards compatible. Currently there is no documentation, feel free to use the demos as a reference and/or read the source code. The engine can render using <canvas> and <svg> so far. WebGL renderer coming soon.

### Usage ###

The library needs to be included first thing.

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

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 in the document.body element.

	<script type="text/javascript">

		var camera, scene, renderer;

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

		function init() {

			camera = new THREE.Camera( 75, SCREEN_WIDTH / SCREEN_HEIGHT, 0.0001, 10000 );
			camera.position.z = 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;
				scene.add( particle );

			}

			document.body.appendChild( renderer.domElement );

		}

		function loop() {

			renderer.render( scene, camera );

		}

	</script>

2010 06 20 - **r9** (23.753 kb)

* JSLinted.
* autoClear property for renderers.
* Removed SVG rgba() workaround for WebKit. (WebKit now supports it)
* Fixed matrix bug. (transformed objects outside the x axis would get infinitely tall :S)


2010 06 06 - **r8** (23.496 kb)

* Moved UVs to Geometry.
* CanvasRenderer expands screen space points (workaround for antialias gaps).
* CanvasRenderer supports BitmapUVMappingMaterial.


2010 06 05 - **r7** (22.387 kb)

* Added Line Object.
* Workaround for WebKit not supporting rgba() in SVG yet.
* No need to call updateMatrix(). Use .autoUpdateMatrix = false if needed. (Thx [Gregory Athons](http://github.com/gregmax17)).


2010 05 17 - **r6** (21.003 kb)

* 2d clipping on CanvasRenderer and SVGRenderer
* clearRect optimisations on CanvasRenderer


2010 05 16 - **r5** (19.026 kb)

* Camera.x -> Camera.position.x
* Camera.target.x -> Camera.target.position.x
* ColorMaterial -> ColorFillMaterial
* FaceColorMaterial -> FaceColorFillMaterial
* Materials are now multipass (use array)
