three.js
JavaScript 3D library
The aim of the project is to create an easy to use, lightweight, 3D library with a default WebGL renderer. The library also provides Canvas 2D, SVG and CSS3D renderers 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.
import * as THREE from 'js/three.module.js';
var camera, scene, renderer;
var geometry, material, mesh;
init();
animate();
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 );
document.body.appendChild( renderer.domElement );
}
function animate() {
requestAnimationFrame( animate );
mesh.rotation.x += 0.01;
mesh.rotation.y += 0.02;
renderer.render( scene, camera );
}
If everything went well you should see this.
