A three-dimension visualization system of marine environment based on OpenSceneGraph
基于OpenSceneGraph的海洋环境三维可视化系统研究

A study on the use of the virtual reality technology in three-dimension (3D) visualization of marine environment was carried on by analyzing and integrating the data of atmosphere, sea-floor relief, wind, wave and current. Methods, such as scene culling, level of details (LOD) and dispatch of dynamic scene, were used, and the data was processed and analyzed with tools including VisualPlanetBuilder (VPB) and ARCGIS. With Visual C++ and OSG 2.8.7 graphics toolkit, a dynamic,interactive and real-time 3D visualized marine environment was constructed, which can be used as a convenient and direct 3D graphic tool for marine science research and engineering.
