The Studying And Realizing Of Several Technologies In The Virtual Campus

The virtual campus is the concrete application of the virtual reality technology in the digitized campus. Through the virtual campus, people can visit and plan the scene of the real campus on the computer, the more important thing is that we can set up a virtual university in three-dimension based on the platform of the virtual campus, offering corresponding online education, etc..The thesis recommends the structure and technology of the virtual campus system and provides a frame structure of the virtual campus system that can meet basic demand, and on this basis, further investigates and explores several technologies which supported the system of virtual campus:In order to present the virtual 3D object, direct against the characteristics of the scene structure and OPENGL, we use the data structure with stripes of triangle, thus we can show and operate the 3D object conveniently.We introduce the relevant technology of the interface in detail, and develop the corresponding interface, and further improve the part of the material and texture-map to make the interface more practical and high efficient.In the thesis various kinds of mutual ways have been analyzed to solve the problem of interactive operation.The thesis adopt interlacing array, display List, model simplification and multi-resolution model, etc. to accelerate the systematic speed of operation.Considering the implement experience and the deficiency of our system, we make a simple prospect to several aspects needing further investigating for the future in the thesis.
