【摘要】 针对海洋工程领域仿真可视化的需求,在OpenGL平台下,以电子海图为基础,对海洋基本地理特征的构建和可视化开展了针对性的研究工作,通过研究海底地形和地物数据的特点,采用了不同的建模方法和实时显示方法,并搭建了二、三维可视化联动的系统架构。最后通过相应的试验工作验证了相关方法的正确性。系统成本低廉、运行高速,可以真实地重建海洋地理特征,为获取和感知准确全面的海洋基本地理特征信息环境打下了基础,具有一定的理论意义和工程应用价值。更多还原

【Abstract】 For the requirement of visual simulation in the field of ocean engineering,the primary work for reconstruction and visual simulation of oceanic basic geographical feature was processed based on the data provided by electronic navigation chart under OpenGL platform.Different model and real-time display method were adopted according to the character of seabed terrain and surface features;at the same time a dynamic switch system between two-dimension and three-dimension was established.Through corresponding experiment the validity of those methods was proved.The system has low cost and high speed,and it can provide actual oceanic geographical feature environment,as a result it establishes a foundation for obtaining and apperceiving exact and comprehensive information of oceanic geographic features.It has definite value in theory and engineering.更多还原
