ABSTRACT:
A spherical projection system includes a spherical rear projection screen assembly of an extent such that a viewer sees projected images in any viewable direction, a plurality of image projectors which cooperate to project portions of a continuous panoramic scene onto all the viewable surfaces of the screen assembly, sets of mirrors to reflect the images onto associated areas of the screen assembly, and an opaque enclosure which houses the screen assembly, mirror sets, and image projectors. In one embodiment of the system, the screen assembly includes a truncated spherical portion which is sized to receive a viewer entirely within and which is closed by a planar rear projection screen which forms a floor to support the viewer. A separable section of the spherical screen portion is mounted on a track for sliding movement to allow entry and exit by the viewer. In another embodiment of the system, the spherical screen is sized to receive only the head and upper body of the viewer. The spherical screen is rotatably mounted to allow the viewer to turn it to see all portions of the projected images.
