"Backside" of polygons not displaying

[GoogleCodeExporter]

You can see here:

If you look at the "bottom" of the vase there, it is rendering; but if you look 
through the "top" or "opening" of the vase, you can see the bottom of the base 
is not rendering.

Is there a way to make the "backside" of the polygons the same as the 
"frontside" or render them as black or something?

Oh, the back faces there are culled. You can change the default behaviour by 
adding the following lines immediately after the initilization codes of the 
viewer:

  viewer.onloadingcomplete = function() {
    var scene = viewer.getScene();
    if (scene) {
      scene.forEachChild( function(mesh) {
        mesh.isDoubleSided = true;
      } );
    }
  };

This marks all parts of the model to be double-sided, when the loading is 
complete, which tells the viewer to disable back-face culling on them.
