Scientific Journal of Information Engineering June 2013, Volume 3, Issue 3, PP.50-55 Design of 3D Virtual Campus Roaming System # Hongyan Yang, Zhuo Shi, Yanru Zhong College of Computer science and engineer, Guilin University of Electronic Technology, Guilin Guangxi 541004, China #Email: rosezhong@ Abstract With the growing sophistication of virtual reality technology, 3D virtual campus roaming system as effective platform for school propaganda outside, the campus planning and management decision will provide a strongly support. Taking the campus of Guilin University of Electronic Technology as prototype, combing with the software of 3Ds Max and using VR-Platorm development platform connections with the backend database and virtual building and live Imaging shooting, a real-time roaming system of virtual campus has been designed and implemented. In this paper, the main aim is to explore a new idea for digital campus construction.
