摘要
结合虚拟现实技术在水利工程三维可视化系统中的应用,通过对流域地形仿真、洪水演进模拟的三维可视化研究,以等高线数据为基础,使用VPB及ArcGIS构建地形模型,采用VC++结合OSG的可视化开发环境建立了水利工程可视化模拟系统,实现了三维场景漫游、空间信息查询、洪水演进模拟等功能。该系统能在PC机上流畅地运行,图形的生成速度和质量较高。
Combining virtual reality technology application in hydraulic engineering three- dimensional visualization system, this paper studied on terrain simulation and flood routing simulation. With contour data, it employed VPB and ArcGIS constructing terrain model, adopted VC ＋ ＋ and OSG developing environment to establish hydraulic ongineering visualization simulation system, realized the 3D cruising, spatial information inquiry and flood routing simulation. The system can be applied in PC with high speed and quality for graphic generation.
