Abstract: Two-dimensional aerial images and other geo-spatial information are processed to produce land classification data, vector data and attribute data for buildings found within the images. This data is stored upon a server computer within shape files, and also stored are source code scripts describing how to reconstruct a type of building along with compiled versions of the scripts. A software game or simulator executes upon a client computer in which an avatar moves within a landscape. A classifier classifies a type of building in the shape file to execute the appropriate script. Depending upon its location, a scene composer downloads a shape file and a compiled script is executed in order to reconstruct any number of buildings in the vicinity of the avatar. The script produces a three-dimensional textured mesh which is then rendered upon a screen of the client computer to display a two-dimensional representation of the building.
