First Claim
Patent Images
1. A method of displaying an image on a curved viewing surface, said method comprising:
- providing a virtual surface in a computer-readable memory that is a representation of the curved viewing surface; and
texturing said virtual surface with the image pursuant an angular distribution using a graphics processing module to thereby form a textured virtual image.

Abstract
An image display system for displaying a planar image on a curved viewing surface, such as a theater dome, with minimized image distortion. In order to display the image, a virtual surface, which is a representation of the curved viewing surface, is textured with the image using an angular distribution to thereby form a textured virtual image. The textured virtual image is then displayed onto the curved viewing surface.
