VR is a integrated technology, involving computer graphics, human-computer interaction technology, sensor technology, artificial intelligence and other areas, it use computer generation vivid 3D view, listen to, smell and feeling, make the person as a participant through proper device, naturally in the virtual world into the experience and interact. When the user moves the position, the computer can immediately carry out complex operations, the exact 3D world image sent back to produce a sense of presence. The technique integrates computer graphics (CG) technology, computer simulation technology, artificial intelligence, sensor technology, display technology, network parallel processing technology of the latest achievements, a simulation system of high technology aided by computer technology generation. In Wuhan University of science and technology, South environment as a virtual space, shooting teaching building, library, gymnasium, living quarters, roads, trees, gardens, pavilions and other outdoor scenes generated panorama, virtual campus roaming, and for the user to provide keyboard, mouse and other control means and way of human-computer interaction.
