RESEARCH ON OPENGL BASED MODELING AND ROAMING TECHNOLOGY IN VIRTUAL ENVIRONMENT

摘要

Virtual reality technology is an important developing simulation technology, it covers many advanced modern techniques such as artificial intelligence, computer graphics, human computer interaction, multimedia and real-time computation, and brings a true experience to users, in this paper, the characteristics of virtual reality technology and the virtual campus roaming system is researched. Based on geometrical modeling technology, the architecture of the whole virtual campus system as well as the scene modeling is accomplished. Then the methods and strategies of how to roam in the virtual construction are confirmed. By Visual C++ 6.0 and OpenGL language, the virtual environment according to our teaching building is set, and its modeling and the real-time roaming are achieved.
