Design And Realization Of An Interactive Virtual Campus Roaming System Based On VRML

The virtual campus is the concrete application of the virtual reality technology in the digitized campus. Virtual Campus can show the realistic campus, people can surf on net and design the school situation by the virtual campus reality equipment. The three-dimensional virtual university can be built in this foundation, so other corresponding online education can be offered too. Through the virtual campus, people can visit and plan the scene of the real campus on the computer.This paper studies the virtual campus roaming system for the technical issues involved in a more systematically, and under the computer environment, to realize a combination of an indoor and outdoor system and emphasize interactive virtual real-time roaming Shan Xi Vocational and Technical College of Finance and Trade System by Virtual Reality Modeling Language (VRML) and 3DS MAX. This paper mainly studies in the following three aspects of the exploration:1. To construct a realistic virtual three-dimension scene system is the basic work of the entire campus. Using 3DS MAX, VRML 3D virtual campus and explore ways to reduce the complexity of the scene and truly used these methods to reduce the complexity of the scene demands.2. We must consider the optimization of the scenes, when we create the scenes. Because of the size of the VRML file decided the transmission speed and load it on the Internet browsing speed of the memory. To improve the visiting speed, the system uses a variety of VRML file optimization strategy to achieve the objective of reducing paper capacity.3. This paper is not only realize the basic functions of virtual entities manipulated by using VRML a human-machine interaction mechanisms in the course of roaming, but also realize a dynamic entity to change the color and texture of interactive design. The system is a real-time, interactive and a good visual effect. Users not only can visit the campus, but also can visit the scenes of some simple real-time interaction. Interactive is in the form of relatively simple, so we will improve it for future.
