I tried a couple of different ways to overlay text on-top of 2D-3D view. There are solutions but almost all of them need the position for parent div to be relative which doesn't work with our 3D view. I'm not sure if this is an error with Spectacles or my design. It works fine for 2D images. Ah! :|
