| 摘 要： | 数字校园是数字城市的缩影,是虚拟校园建设的支撑平台。在综合分析现有三维数字校园建设的基础上,以山东科技大学青岛校区为例,引入ArcGlobe软件,讨论了数字校园建设的数据来源与处理方法、三维校园仿真的技术流程、不同起伏度的地面三维模型的构建方法、地物景观模型的构建技术等。给出了三维校园仿真的具体实现方法,采用LOD和动态纹理匹配技术提高了三维建筑物加载和绘制的速度。论文给出的数字校园仿真与建模的方法对正在开展的数字校园与数字城市建设具有较强的指导意义。

| Abstract: | As a microcosm of digital city and fundamental platform of virtual campus, 3D digital campus constructions are booming with a new climax. In this paper, ArcGlobe （a component of ArcGIS） is employed to simulate the 3D campus. By taking Qingdao campus of Shandong university of science and technology as a case, various data sources and their corresponding processing methods are analyzed, specific technological route of whole digital campus simulation is proposed, the creation of 3D digital terrain modeling in different area with different surface rolling is given, the way to create 3D building modeling specially is emphasized. Also, LOD and dynamic texture match are illustrated since they raise signally the speed of loading and drawing. The experiment presented in this paper is proved to be more reasonable and efficient in 3D digital campus construction. |
