Paper Abstract

The scene content and fidelity of Computer Image Generators (CIG) has increased dramatically in recent years. Photographic source data is now being used in today's real-time visual simulators, and the expectation is that it will be used to a much greater extent in the next generation ofvisuals. Photographic source will be used to extract traditional CIG cultural features such as roads, rivers, and fields, expressed geometrically as polygons and radiometrically as photo textures. In addition, overhead aerial and satellite photography will be applied to the terrain surface as photo texture, resulting in the need for multigigabyte on-line image data bases. At the same time, highly accurate representations of the terrain and the 3-D features on the terrain surface will be supported by these advanced systems. Data bases will be extremely dense, with near-continuous scene density for both 2-D (photographic) and 3-D (polygonal) features. The emerging requirement for mission rehearsal capabilities in a visual simulator will continue to increase the needed data base fidelity, while imposing a severe time constraint on data base construction. The Rapidly Reconfigurable Data Base (RRDB) Project, funded by PM-TRADE under the USAF/ASD Project 2851, proposes to develop a data base generation system capable of constructing a data base in 72 hours; the Special Operations Forces have specified an Aircrew Training System with a 48-hour data base turnaround requirement. This paper will discuss how traditional CIG architectures and companion data base generation systems have been impacted by the addition of photo-based visual technology, and the emergence of mission rehearsal applications.
