【Abstract】 In the three-dimension Electronic Chart Display System, the high-efficient and the high-lifelike simulation realistic scene is one of important focuses. So how to obtain the accurate scene data and lifelike scene displaying is a key problem. This paper studies the model data collection and model construction in 3D ECDIS, and using OPENGL three-dimensional graphic technology and region subdivision displaying. The system can meet the requirements for designing a virtual scene and satisfy the virtual sea.更多还原
