Scene Modeling And Roaming Systems Of The Virtual Campus To Achieve

The Virtual Walk-through technology is an important content of Viriual Reality technology,it was developed in architecture,junketing,gmae,aviation spaceflight,medicine fastly. Because of it's important 3I characteristic—immersive,intercooperation,imaginative,so the other Walk-through technology has no advantage compared to it.Virtual Campus is an important application of Virtual Walk—through technology,Virtual campus can provide virtual enviornment,it also can support the resource management,environment Porgramming,campus evolution and the 1on- distance accessing of the real campus. So the Virtual campus will be the most important direction of informational evolution of campus.The purpose of this study is to discuss the scene modeling, interaction, walk-through and information search technology in virtual system. The author studied Virtual Reality technology deeply,analyzed and compared various sorts of modeling technology by reading a great deal of correlated documents from home and aboard. Basing on this,the construction scheme of Virtual Reality System,which adopts the technology of nd Browser's plug-in,is proposed. On this basis, determine based on DirectX and C++ virtual campus roaming system architecture program.This thesis mainly focused on the modeling of three-dimensional scene through 3DMAX and DirectX combination as modeling methods.First of all, according to the clues of virtual environment construction flow, with the"vitual-real"combination method to realizing the complex and static models. In the vitual sence, models often can't as the same as the real sence, and it can't rendering the sence in real-time, in view of this contradiction, we give the principle of models design, and also optimized the virtual campus modeling.Second, we discussed how to realize the interaction function between users and the virtual sence in virtual reality roaming system, used DirectInput module in DirectX. Use the camera transform, this system implement the sence's real-time cut .Third, this paper introduced collision detection technology in virtual reality sence, and used AABB surrounding box to detect the collision in this sence. At last, Comprehensived all the reaserch above, designed and realized a virtual campus roaming system based on the combination of DirectX and C++ technology, and test the effect of this roaming system.
