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, wherein the p-surface comprises polygons approximating a partial sphere;
selecting a direction of view within the p-surface;
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; and
displaying a predetermined portion of said 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, selecting a direction of view within the p-surface, 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, and displaying a predetermined portion of the texture mapped p-surface. An apparatus for implementing the method is also described.
