摘要
从3D GIS的需求出发,实现了一种适合在大区域范围内仿真不规则河道中水流的方法。该方法综合研究了在大区域环境下仿真水流的LOD方案、场景数据组织与调度、水面建模方法以及水面反射、波浪、动态高光等现象的模拟方法。在金沙江下游梯级水电站水文泥沙数据库及信息管理分析系统中的应用证明了该方法的可行性。
Considering the needs of 3D GIS,a water simulation method for large area irregular riverway is accomplished,in which we study a comprehensive method of LOD method for water simulation in large area,scene data organization and scheduling,water surface modeling method as well as simulation methods of water surface reflection,water wave and dynamic water high lights.The application to Jinsha River hydrologic and sediment information system show the feasibility of the method.
