How it works

The <FormatModel> creates a camera, scene, light source and a WebGL renderer.The DOM returned by the renderer (a <canvas> element) is added to the document and configured to fill the viewport. Scene is rendered in real time. In the componentDidUpdate method, the changes of props are detected and the attributes of objects are changed.
