#### JavaScript 3D library
|
||
|
|
|
||
|
|
The aim of the project is to create an easy to use, lightweight, cross-browser, general purpose 3D library. The current builds only include a WebGL renderer but WebGPU (experimental), SVG and CSS3D renderers are also available as addons.

### Usage
|
||
|
|
|
||
|
|
This code creates a scene, a camera, and a geometric cube, and it adds the cube to the scene. It then creates a `WebGL` 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.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
import * as THREE from 'three';
|
||
|
|
|
||
|
|
// init
|
||
|
|
|
||
|
|
const camera = new THREE.PerspectiveCamera( 70, window.innerWidth / window.innerHeight, 0.01, 10 );
|
||
|
|
camera.position.z = 1;
|
||
|
|
|
||
|
|
const scene = new THREE.Scene();
|
||
|
|
|
||
|
|
const geometry = new THREE.BoxGeometry( 0.2, 0.2, 0.2 );
|
||
|
|
const material = new THREE.MeshNormalMaterial();
|
||
|
|
|
||
|
|
const mesh = new THREE.Mesh( geometry, material );
|
||
|
|
scene.add( mesh );
|
||
|
|
|
||
|
|
const renderer = new THREE.WebGLRenderer( { antialias: true } );
|
||
|
|
renderer.setSize( window.innerWidth, window.innerHeight );
|
||
|
|
renderer.setAnimationLoop( animation );
|
||
|
|
document.body.appendChild( renderer.domElement );
|
||
|
|
|
||
|
|
// animation
|
||
|
|
|
||
|
|
function animation( time ) {
|
||
|
|
|
||
|
|
mesh.rotation.x = time / 2000;
|
||
|
|
mesh.rotation.y = time / 1000;
|
||
|
|
|
||
|
|
renderer.render( scene, camera );
|
||
|
|
|
||
|
|
}
|
||
|
|
```

### Cloning this repository
|
||
|
|
|
||
|
|
Cloning the repo with all its history results in a ~2 GB download. If you don't need the whole history you can use the `depth` parameter to significantly reduce download size.
|
||
|
|
|
||
|
|
```sh
|
||
|
|
git clone --depth=1 https://github.com/mrdoob/three.js.git
|
||
|
|
```
|
||
|
