| Abstract: | In order to achieve the three-dimensional integrated visualization of marine scalar data which has features including massive volume, multiple-sources, heterogeneous, multi-dimensional, multi-format, dynamic in structure and time. A service-based three-dimensional virtual visualization architecture was designed for generic scalar data format. The marine 3D visualization prototype system was constructed, and the system function design and implementation were elaborated. The geometry-graphic method, together with LOD dynamic scheduling, surface texture and fast query and other key technologies were used to achieve a series of functions including three-dimensional dynamic visualization of marine scalar field data, marine element values queries, time series analysis and so on. The study can provide a good solution for the visualization and analysis to the other marine environmental data. |
