水利工程三维可视化仿真研究与应用

针对目前水利工程建模过程复杂和效率低等问题,提出基于World Wind的水利工程三维建模方法。设计了三维建模流程,基于World Wind搭建三维数字地球平台,构建三维可视化模型,并实现模型在平台上的加载与管理。以陕西省引汉济渭工程为例,建立可视化环境,开发水库三维模型,并在数字地球平台上实现水库模型的加载与展示。实例表明:基于World Wind的数字地球平台具有较好的扩展性与可视化效果,提出的水利工程三维建模方法能够有效实现水利工程的三维可视化仿真,具有较好应用价值和推广前景。

Study and application on three-dimensional visualization and simulation for water project

In the light of the problems of complex and low efficiency in the process of engineering modeling, the paper proposed a three-dimensional modeling (3DM) method of water project based on the WorldWind.It designed the process of 3DM,established the three-dimensional digital earth platform based on the WorldWind,and realized the loading and. Management of model on the platform. Taking the Han-to-Wei River project for example,the paper established the visualization environment and developed the 3DM of reservoir,which was then integrated and displayed on the digital earth platform.The results show that the digital earth platform based on WorldWind has better scalability and visual functions. The method can efficiently achieve the three-dimensional visualization and simulation of the water project and has good application value and popularize prospect.
