Design And Research Of Virtual Simulation Campus

In twentieth Century90，Virtual reality technology has been developed. Ascomputer technology， It can use computer graphics technology，3D technology,simulation technology, speech recognition technology， multimedia technology,network technology and other techniques to simulate a real virtual world. People canthrough the visual, auditory, tactile and olfactory perception as tothe real environmentand virtual environment in this virtual world，so as to achieve the feeling of bepersonally on the scene.As the development language of virtual reality, a lot of3D model constructingsoftware file format can combine with VRML language. At the same time, theextended VRML can also realize its function by Java language and JavaScriptlanguage. The combination of the three makes the development of virtual realitysystem more convenient and powerful.In recent years, as a new subject of virtual reality, the virtual campus has beenrapiddevelopment. This paper researchs and analyzes the virtual campus of HainanCollege of Software Technology, including the virtual technology,3D technology etc.conducts the research from thevirtual technology,3D technology etc.. This papergives a detailed analysis of the development of virtual reality technology,three-dimensional modeling technology, the realization of virtual reality technologyand other related content.The following is the main contents of the thesis:1. On the construction of the three-dimensional modeling technology was studied,including: how to complete the production of various types of3D model in3ds Max, how to export the3D model format in accordance with the requirements of VRMLfile format, how to optimize the3D model, how to optimize the material(map) etc.2. On the VRML language to develop the virtual system technology wereintroduced and analyzed, including: to explain in detail the view technology, toautomatic roaming and interactive roaming technology, and the collision detectionproblem existing in the system were solved.3. The JDBC technology was discussed, to study it in the system how to usethese two kinds of technology to realize virtual system query function.At the end of this thesis, the total research contents were summarized and thefuture research work was prospected.
