#### JavaScript 3D library ####
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|

### Usage ###
|
||
|
|
|
||
|
|
Download the [minified library](http://threejs.org/build/three.min.js) and include it in your html.
|
||
|
|
Alternatively see [how to build the library yourself](https://github.com/mrdoob/three.js/wiki/build.py,-or-how-to-generate-a-compressed-Three.js-file).
|
||
|
|
|
||
|
|
```html
|
||
|
|
<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.

|
|
|
||
|
|
```html
|
||
|
|
<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>
|
||
|
|
```
