three.js's Introduction

three.js

JavaScript 3D library

The aim of the project is to create a lightweight 3D library with a very low level of complexity — in other words, for dummies. The library provides <canvas>, <svg>, CSS3D and WebGL renderers.

Examples — Documentation — Migrating — Help

Usage

Download the minified library and include it in your html. Alternatively see how to build the library yourself.

<script src="js/three.min.js"></script>

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.

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

init();
animate();

function init() {

	scene = new THREE.Scene();

	camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 1, 10000 );
	camera.position.z = 1000;

	geometry = new THREE.BoxGeometry( 200, 200, 200 );
	material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );

	mesh = new THREE.Mesh( geometry, material );
	scene.add( mesh );

	renderer = new THREE.WebGLRenderer();
	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 );

}
