Abstract
A three dimensional display system comprises a display volume selectively partitioned into distinct display regions, a display surface for scattering light beams from the display volume, at least two optical scanners for modulating the light beams and for directing the light beams to the display surface within each distinct display region respectively, and a display controller. The display controller comprises a world coordinate interface for inputting world coordinates, a data processor for transforming the world coordinates into view coordinates and device coordinates, and an optical scanner controller for sensing and controlling the motion of the display surface and for outputting the device coordinates to the optical scanners to generate a three dimensional image within the display volume.
