Abstract (en)
[origin: WO9904563A1] A projection display system with virtual reality capabilities. The system comprises a multi-pipe graphics engine (27) having a controller (16) cooperating therewith to produce a plurality of different video signals. The system also includes a plurality of projectors (14) which project video images corresponding to and upon receipt of the video signals from the graphics engine and the controller. A screen (30) is positioned relative to the projectors to have the video images projected thereon. The screen, having a top, sides and a bottom, is constructed without supports along the bottom which would interfere with the projection of the images from the projectors completely down to the lowermost bottom periphery of the screen.
