Research of 3D dynamic visualization system for tidal current model

应用GIS技术和三维仿真技术建立三维地形模型,通过叠加二维动态潮流模型实现了潮流模拟三维动态可视化,并给出了系统层次架构模型。在对基础数据进行格式分析的基础上,重点阐述了地形数据处理建模方法和二维潮流动态模拟的空间和时间插值混合使用关键算法,介绍了由此开发的潮流模拟三维动态可视化演示系统的具体功能模块,并对系统深入开发方向进行了展望。

Based on GIS and 3D simulation technology,3D terrain models were established.Then the 3D dynamic visualization of tidal current model was realized by superposition of 3D terrain models and 2D dynamic flow field simulation.The system-level architecture model was also given in this paper.According to the analysis of data format,the topographic data processing and modeling methods and the key algorithms of 2D dynamic simulation with the mix use of spatial and temporal interpolation were discussed.In the end,the function modules of the 3D Dynamic Visualization System for Coastal and Estuarine Tidal-current Model were described,and the direction of in-depth development of this system was predicted.
