| 摘 要： | 运用数字高程模型(DEM)数据格式中的三角网格模型,以OpenGL提供的光照、材质、纹理映射和反走样等技术实现河道地形的三维可视化;利用VC 及OpenGL中的平移、旋转和缩放等功能,实现河道流场三维显示的效果。在读取相关洪水数据的情况下,实现了流场可视化及河道堤坝防洪预警等相关查询功能,为防洪决策提供了相关的参考。

| Abstract: | In order to realize the river way flood flow,this paper focus on the triangular mesh model in the digital elevation model(DEM),using OpenGL method of illumination,material,texture map and antialiasing to realize the multi-dimensional visualization of river way terrain.The modeling transformation of removing,rotate and scaling in VC and OpenGL are also used in order to realize the dynamic displaying effect.Searching functions related to visualization and riverbank flood forecast can be realized after adding flooding data under various conditions.These functions are for the reference of flood control decision-making. |
