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.WebGLRenderer(); renderer.setSize( window.innerWidth, window.innerHeight ); document.body.appendChild( renderer.domElement ); } function animate() { 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.
