PC-based stereo visualization tools for aviation virtual-reality projects

Virtual reality is a new way to enhance the human interaction with a simulator or another man-machine system. Synthetic environment of virtual reality provides new possibilities of human activity due to the use of various sensor channels. Stereo visualization provides human immersion to virtual space and is the important feature of virtual reality. The investigations of technical and programming tools for stereo visualization of highly accurate and detailed 3D models of objects and the terrain with geo-specifically placed objects like buildings, roads, forests and other special landmarks are discussed. Hardware includes liquid crystal shutter glasses and Intel Pentium computer with standard monitor. Use of original photogrammetric and rendering software under MS Windows provides very realistic `walk-through' and `fly-over' simulations. These tools are cheaper than ones oriented to powerful workstations. The examples of animations and virtual spaces with designed for airplane pilot training 3D site models of real scenes are demonstrated.
