Abstract

A projection and display system for reverse projection of imagery includes an imagery projection system having a lens barrel for projecting images. The imagery projection system extends into a substantially closed, geometric viewing surface, such that the lens barrel is disposed at a predetermined distance from and at a predetermined orientation relative to an interior surface of the geometric viewing surface. The images are projected onto an interior surface of the geometric viewing surface. The images may be defined in vector coordinates or in raster coordinates.
