three.js : JavaScript 3D library：javascript

1.下載three.min.js：html

http://threejs.org/build/three.min.jsjava

2. 建立threejs_test.js：瀏覽器

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

function init() {
    camera = new THREE.PerspectiveCamera( 70, window.innerWidth / window.innerHeight, 0.01, 10 );
    camera.position.z = 1;

    scene = new THREE.Scene();

    geometry = new THREE.BoxGeometry( 0.5, 0.5, 0.5 );
    material = new THREE.MeshNormalMaterial();

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

    renderer = new THREE.WebGLRenderer( { antialias: true } );
    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 );
}

3. 建立threejs_test.html文件app

<!DOCTYPE html>
<html>
<head>
    <script src="three.min.js"></script>
    <script src="threejs_test.js"></script>
</head>

<body>
    <script type='text/javascript'>init();</script>
    <script type='text/javascript'>animate();</script>
</body>

</html>

4. 瀏覽器上顯示：dom
