<p>A projection system employs a convex reflecting mirror (20) to disperse a projected image onto the inner surface of a screen (26) enclosing a spherical or other three-dimensional space (17). When the screen is a spherical, translucent rear-projection screen, the projection system produces a display of substantially spherical form viewable from outside the enclosed space. When the screen is opaque and of spherical or other three-dimensional form, the projection system produces a three-dimensional image surrounding a viewer.</p> |
