            Even though this is becoming less and less of a problem, some devices or browsers may still not support WebGL 2.
            The following method allows you to check if it is supported and display a message to the user if it is not.
            Import the WebGL support detection module, and run the following before attempting to render anything.

import WebGL from 'three/addons/capabilities/WebGL.js';

} else {

  const warning = WebGL.getWebGL2ErrorMessage();
  document.getElementById( 'container' ).appendChild( warning );
