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.

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'; 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.
