Visual Simulation Technology Research And Implementation

Virtual real-time navigation of the complicated scene is an important application in visual simulation, which have extensive application outlook in the field of entertainment, touring, education and training, city planning etc. Visual simulation apply computer graphics and images technology, according to the target of simulation to construct the 3D model of the object or reproduction the reality environment, which can achieve vivid simulating effect and access mutual between the user and the environment.The theory of visual simulation and the scene building technology are studied in this paper, for example, the quick modeling technology of virtual scene, the building technology of special effects, the managing of large terrain, the laying of environment light. You must master the application of Vega and MultiGen.In the scene navigation, two scheme are presented according to different request. One is to navigate mutually controlled by mouse , the other is to navigate automatically along the path designed in advance. By modifying the model parameter, it can simulate the observing effect in all directions in the scene.On the base of MultiGen and Vega, a virtual campus is realized.
