The virtual campus system based on SketchUp and OpenGL

Under the current three-dimensional GIS popular tendency, the designing and realization virtual campus system based on SketchUp and OpenGL is a new idea. In this paper, firstly we propose the framework and the technical route of virtual campus system, and then discuss the workflow of three-dimensional campus scene modeling based on SketchUP and the key technologies in the realization of the system. Finally, we develop a virtual campus system of Anhui Normal University by using the technical route and the design proposal in this paper. The experiment result indicates that the technical route and design proposal are reasonable, and the system developed can entirely meet the need of real-time scene roaming in the ordinary PC.
