| Abstract: |
| In order to realize the visualization of multimodal and dynamic data, a multimodal dynamic visualization system was developed using VC++ and CG language. The rendering engine was based on OpenGL three-dimensional standard. A series of mode analysis methods for the marine and atmospheric data analysis were proposed, including probe function, line mode, polygon mode, cuboid mode, vector mode analysis and temporal changes analysis. The system was used to transfermassive marine and atmospheric data into three-dimensional spatial or dynamic evolution images, as well as realize the users interaction processing. Through this system, the visualization technology can be used to analyze long temporal changes of marine and atmospheric data. It turned out that this system can represent the dynamic change process of marine and atmospheric data through the real-time dynamic visualization images. |
