The aim of the project is to create a lightweight 3D library with a very low level of complexity — in other words, for dummies. The library provides <canvas>, <svg>, CSS3D and WebGL renderers.
Examples — Documentation — Migrating — Help
Download the minified library and include it in your html. Alternatively see how to build the library yourself.
<script src="js/three.min.js"></script>This code creates a scene, a camera, and a geometric cube, and it adds the cube to the scene. It then creates a <canvas> renderer for the scene and camera, and it adds that viewport to the document.body element. Finally it animates the cube within the scene for the camera.
<script>
var scene, camera, renderer;
var geometry, material, mesh;
init();
animate();
function init() {
scene = new THREE.Scene();
camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 1, 10000 );
camera.position.z = 1000;
geometry = new THREE.BoxGeometry( 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() {
// note: three.js includes requestAnimationFrame shim
requestAnimationFrame( animate );
mesh.rotation.x += 0.01;
mesh.rotation.y += 0.02;
renderer.render( scene, camera );
}
</script>If everything went well you should see this.
