安徽师范大学三维虚拟校园系统建设研究

随着虚拟现实和三维地理信息系统技术的日趋成熟,三维虚拟校园建设已成为数字校园建设的新热点.本文结合安徽师范大学三维虚拟校园建设的实际需求,分析了三维虚拟校园建设的主要内容和系统实现的总体框架,探讨了数据源的获取和处理、建模软件的选取和应用、三维模型的建立和优化等校园三维建模的技术细节,并研究了模型的快速加载与实时漫游、二三维动态交互、基于插件技术的集成应用框架等系统实现的关键技术.根据本文提出的建设方案和技术方法,采用3DMAX建模软件制作了安徽师范大学三维校园模型,并在VisualStudio 2008平台下,基于OpenGL和.NET类库,采用插件式技术编程实现了安徽师范大学三维虚拟校园原型系统,系统在运行效率、独立性、真实感和可扩展性等方面取得了较好的效果.

Research on the construction of three-dimensional virtual campus system

With more and more matured technology of virtual reality and three-dimensional GIS,three-dimensional（3D） virtual campus construction has become the new focus of digital campus construction.In this paper,in view of the actual demand of 3D virtual campus system of Anhui Normal University,firstly,the main work of constructing 3D virtual campus was analyzed and the general framework and main functions of the system was designed.Secondly,the key technology of campus 3D modeling was discussed,such as how to get and process source data,how to select the appropriate 3D modeling software,how to model the 3D modeling by the modeling sofware and how to optimize the 3D modeling in the modeling sofware.Next,the key technologies of system implementation was studied,such as how to accelerate the modeling loading and real-time roaming,how to provide the convenient interaction between 2D and 3D,and how to build the systme＇s framework based on plug-in technology.Finally,according to the design proposal and key technologies proposed in this paper,the 3D model of Anhui Normal University Huajin campus by 3DMAX,and was programed to implement the 3D virtual campus prototype system of Anhui Normal University in visual studio 2008 based on OpenGL and.Net class library.The experiment result shows that the desing proposal and key technologies proposed in this paper are feasible,and the prototype system is effcient,high independent,high realistic and high scalability.
