Development Of Visual Walkthrough System Of The Campus

In the recent years, Virtual Reality technology has been widely used in many fields such as city planning, engineering, medicine and travel. As one of the most important parts in the research of VR system, the visual walkthrough technology enables users to view and experience the virtual environment freely with interactive technology. Using the campus of NUAA as virtual environment, visual walkthrough based on virtual reality was discussed in this paper. The research contents in this paper are as follows:Firstly, the important technology of visual walkthrough is researched, it compares with two modeling software and gives the basic way about modeling in the paper.Secondly, it gives the deep research on the key technology of the visual walkthrough in the paper, especially about three-dimension modeling technology, realistic modeling technology and walkthrough technology.Finally, we study the visual walkthrough technology on VR and reached the visual walkthrough system. From three-dimension's reality and real-time characteristic, the model should be built using 3DMAX and Creator firstly, then I study the optimization of the model, some problems in the system-reaching such as storing problem are worked out. At last I fulfill the visual walkthrough system using walkthrough software Vega and have some development with VC, the visual walkthrough system is shown.
