Abstract :
The methodologies introduced here generate photographically realistic 3D worlds from 2D photographic images instead of from 3D geometrical models. If we call conventional methods “algorithm intensive”, these methods are “data intensive”. Several prototype systems, including the Virtual Dome and Camera with GPS, serve as examples. Of course, both types have their advantages, so trade-offs and combinations of the two are also discussed briefly
