TiltViewer was built using Away3D, a branch of Papervision. Currently Away3D provides better handling of mouse events for nested 3D Objects. One limitation of Away3D is that there is no access to a 3D object’s sprite, so you can’t apply filter or alpha effects. I’m guessing that soon these features will be added to both engines.
Does a 3D UI give more functionality than the equivalent 2D interface? No, but its certainly a lot cooler! Part of the motivation to build this was to explore ways to make 3D interfaces simple and intuitive.
Being able to load Flickr images into a 3D engine was recently made possible when Flickr added crossdomain XMLs to it’s image servers. Thanks Flickr!
