Construction of Scene Database in Distributed Simulation

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.
