This paper constructed the overall framework of a real-time virtual campus, and achieved the modeling, environment setting and routing path generating with Multigen software. The puzzles in geometric modeling and virtual scene construction were also discussed in this paper, while the real-time routing was finally achieved in the virtual campus system. The content above would be helpful for the further...
