A prototype of a new form of visualization system is described and its applications are discussed. "Mirage" is a 3D, stereoscopic, pseudo-holographic display system which generates an image that appears as a scale model resting on a horizontal table top in front of the viewer. The viewer may walk around the display, examining the image from various azimuths and altitudes or he may pan and zoom through the virtual space.

The system was developed at the Institute for Simulation and Training to be an "Ultra-Stealth" for viewing Distributed Interactive Simulation exercises but it could also be used to make sonar tracks, fluid flow patterns, logistics status, or other complex multidimensional data sets more easily understood. Of particular interest is the fusion of abstract data, such as graphical representation of network connectivity, battlefield graphical control measures, tactical communications links, and simulation management functions with the 3D representation of terrain and simulation entities. The unusual application of graphical transformations and projection algorithms is explained and promising application areas are discussed.
