Three.js is a lightweight Javascript 3D Engine with a very low level of complexity – in other words, for dummies. The engine can render to the typical 2D , the new WebGL 3D , and . With 20 lines of code, you can easily create a camera, then create a scene, add a cube on it, create a renderer and add its viewport in the document.body element.
