The Research And Implement Of Virtual Campus Based On GIS

In recent years, the application and research of virtual reality developped rapidly. It is a research field which involves the multitudinous technologies,they are the computer graphics,the artificial intelligence, multimedia technology and the human machine interface technology and so on . In many aspects, virtual reality has good development and bright future. The virtual reality is becoming one of the main computer applications and research directions.The paper is to solve the problems which the virtual reality at present spends too much money and is difficult to carry out. We build a system which based on the microcomputer, that is a virtual walkthrough system that can run on PC platform. This system does the research on taking campus of Harbin Engineering University as the research object. It has realized the 3D display of large-scale scene and interactive roaming function. In addition, the system also develops the GIS index system. Above the ground there is the campus with buildings, roads, plants and so on. Underground subjects includes the 3D pipelines with many different kinds of functions. Through the reappearance of three dimensional pipeline positions, the users will understand the position and stretch trend of the pipelines. This paper did the following works:1.Introduce the concept and characteristic of Virtual Reality and GIS. Then expound the technical structure.2.Discuss several manufacture methods and processes in making three dimensional construction models to make the Harbin Engineering University Virtual Campus.3. Do the research about how to roam the scene conversion...
