大规模城市三维景观实时浏览解决方案研究及实现

A Project to Browse a Large Scale 3D Scene of City in Real-time

如何实现大规模城市三维景观实时快速浏览是城市景观可视化中的关键问题之一。主要从空间数据组织、管理、调度方面讨论了这一问题,给出了以多层次细节模型简化技术和动态可见裁剪技术为主要技术的解决方案,最后介绍了一个开发城市三维景观实例系统M3DVIEW。

It is one of key problems for 3D visualization of city how to browse a large scale 3D scene of city in real time.The paper discusses this from several aspects,including the organization,management and dispatch of spacial data and presents two primary techniques for this problem which are LOD and dynamic visibility culling.Finally,a system developed by the authors according to the project is presented as an example.
