Basics of three.js
- Scene
- Objects (Meshes with Materials, Lights, Groups)
- Camera (Perspective, Orthographic)
- Renderer (CanvasRenderer, WebGLRenderer, SVGRenderer, SoftwareRenderer)
var scene = new THREE.Scene();
var object = new THREE.Object();
var aspect = window.innerWidth / window.innerHeight;
var camera = new THREE.PerspectiveCamera( 75, aspect, 0.1, 1000 );
var renderer = new THREE.WebGLRenderer();
scene.add( object );
renderer.render( scene, camera );Working with the CSS3DRenderer
