摘　　要：为了实现海量、多维、时序等特点的海洋环境数据三维动态可视化表达,设计基于OSGEarth三维虚拟可视化平台,并详细阐述该系统的体系结构。将几何着色器应用于对数据的渲染着色,同时利用GPU强大的处理能力加快渲染的速度;通过坐标变换,将数据可视化的结果紧密贴合在三维地球表面上;通过人机交互机制,进一步实现了海洋环境数据的动态可视化。实验表明,该方法具有一定的可操作性,可以为海洋环境数据的动态可视化及分析提供技术平台。To achieve the 3 D dynamic visualization representation of massive and multidimensional marine environment data in time series,the 3 D virtual visualization platform based on OSGEarth is designed,and the architecture of the system is described in detail. The geometry shader is applied to the color rendering of data. Meanwhile,the powerful processing capability of GPU is utilized to accelerate the rendering speed. The date visualization results are closely attached to the surface of the three-dimensional earth by means of coordinate transformation. The dynamic visualization of marine environment data is further realized by using the human-computer interaction mechanism. The experimental results show that the method is feasible and can provide the technology platform for dynamic visualization and analysis of marine environment data.
