GitHub - mrdoob/three.js: JavaScript 3D Library. (original) (raw)
three.js
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 WebGL and WebGPU renderers but 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.
import * as THREE from 'three';
const width = window.innerWidth, height = window.innerHeight;
// init
const camera = new THREE.PerspectiveCamera( 70, width / height, 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( width, height ); renderer.setAnimationLoop( animate ); document.body.appendChild( renderer.domElement );
// animation
function animate( time ) {
mesh.rotation.x = time / 2000;
mesh.rotation.y = time / 1000;
renderer.render( scene, camera );}
If everything goes well, you should see this.
