How is this not just CG/video compositing? I'm not getting the point here. Mapping out the real world shots and camera angles for creating of CG elements is pretty much standard fare for any composited effects shot.
Oh, OK. So it's just a real-time tracker, allowing for 3d compositing on the fly. With interactive CG stuff, possibly. That's kind of cool. Not a huge leap from what they've been doing in the post production world, but it would be cool to see consumers be able to play games based around the concept.
