摘　　要：详细介绍了视景数据库的构造过程,讨论了构造过程中等距网格和三角形不规则网格两种地形模型的优缺点,文化特征物与地形的三种整合方法和多种细节层次的表示等关键技术,然后阐述了视景调度的算法及其与构造的关系。The construction process of scene database is introduced in detail. Some key technologies which are used during the construction process are discussed, such as the advantages and disadvantages of equal sampling interval terrain model and triangulated irregular network terrain model, three integration methods of culture feature and terrain, and the level of detail representation of terrain. Then the scene paging algorithm and the relationship of paging and construction are provided. Furthermore, one example which is implemented in DVENET is given. Finally, problems which are found during the development of DVENET scene database and its future solutions are discussed.
