Method for interactive viewing full-surround image data and apparatus therefor
DC CAFCFirst Claim
1. A method of modeling of the visible world using full-surround image data, said method comprising:
- selecting a view point within a p-surface; and
texture mapping full-surround image data onto said p-surface such that the resultant texture map is substantially equivalent to projecting full-surround image data onto the p-surface from said view point to thereby generate a texture mapped p-surface.

Abstract
A method of modeling of the visible world using full-surround image data includes steps for selecting a view point within a p-surface, and texture mapping full-surround image data onto the p-surface such that the resultant texture map is substantially equivalent to projecting full-surround image data onto the p-surface from the view point to thereby generate a texture mapped p-surface. According to one aspect of the invention, the method also includes a step for either rotating the texture mapped p-surface or changing the direction of view to thereby expose a new portion of the texture mapped p-surface. According to another aspect of the invention, a first the texture mapped p-sphere is replaced by a second texture mapped p-sphere by interactively selecting the new viewpoint from viewpoints within the second texture mapped p-sphere. A corresponding apparatus is also described.
