Not really, big, higher res, more power, same solid UI, same interface...
Image feeding a few still shots of a onset location. It builds a 3d model of the set, and you can then setup networked cameras where you want them placed. You can view from your iPad an overhead view of the set rendered, and the place and feild of view of the cameras. You could then put in some actor avatars and see what the shots are going to look, and you can point at each camera and view what its going to look like. And you can change your camera locations and it shows the change, all on your directors screen.
