three.js
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.

<script src="js/Three.js"></script>
This code creates a camera, then creates a scene, adds a cube on it, creates a <canvas> 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.Camera( 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.addObject( 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> Change Log
