#### 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 in the examples.

### 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 './js/three.module.js';

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

init();

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( 0.2, 0.2, 0.2 );
	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 );
	renderer.setAnimationLoop( animation );
	document.body.appendChild( renderer.domElement );

}

function animation( time ) {

	mesh.rotation.x = time / 2000;
	mesh.rotation.y = time / 1000;

	renderer.render( scene, camera );

}
```

If everything went well, you should see [this](https://jsfiddle.net/vy29n6aj/).

### 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
```
