摘要
为了实现多种海洋标量数据在网络环境下的三维可视化,设计基于开源三维地球框架Cesium的海洋标量场数据可视化系统,三维数据可视化系统采用B/S架构。文中对系统整体架构和功能设计进行详细阐述:系统采用瓦片思想,运用层次细节和数据动态调度方法优化数据可视化效果;系统实现数据的时间过程动态可视化、要素点属性查询和点过程曲线查询等功能。实验结果表明,该系统框架方法具有可行性,可在海洋环境分析中起到一定辅助作用。
A marine scalar field data visualization system based on the open-source 3D terrestrial framework Cesium is designed to achieve the 3D visualization of various marine scalar data in the network environment. The B/S architecture is adopted for the 3D data visualization system. The overall architecture and function design of the system are illustrated in detail in this paper. The data visualization effect is optimized by using the tile thought and the level of detail(LOD)and data dynamic scheduling methods. The dynamic visualization of data′ s time process,queries of element point property and point process curve,and other functions are realized in the system. The experimental results show that the system framework method has feasibility and can play a supplementary role in marine environment analysis.
