- Shiphandling simulator is a device that can partly imitate the true environment at sea ， and is specially designed to satisfy marine education and trains and maritime research etc . one of its key techniques is to create the virtual environment at sea ， and the terrain is its important component . according to the needs of the real time visual display of the shiphandling simulator ， this paper analyses the requirements of the geometry precision of the important islands and background hills which are within the ships ' visible scope ， and brings forward the modeling methods of the hill ' s pileup and the hill ' s silhouette edges based on contour lines . it also presents the definition of error that the hill ' s silhouette edges graph has been given and the effective scope of application ， and firstly established the error criterion of terrain model that is built in shiphandling simulator . with these two kinds of method ， the size of data storage can be minimized greatly ， and the requirements of high update rate and geometry precision for the real time visual display of the shiphandling simulator can be satisfied
船舶操纵模拟器是一种能够部分模仿海上真实情况,专门为满足航海教育与培训、航海技术研究等目的而设计研制的装置，其核心技术之一是海上视景模拟，而地形地貌是海上视景中的重要组成部分.根据船舶操纵模拟器实时视景显示的需要，在分析航行船舶对可视范围内重要岛屿与背景山脉的几何精度要求的基础上，提出了基于等高线的山形堆积建模和山形轮廓建模方法，并给出了山形轮廓图形的误差定义、有效适用范围，以及船舶操纵模拟器中地形建模的误差准则，该方法生成图形的数据量较小，其图形更新速率与几何精度能达到船舶操纵模拟器实时视景显示的要求
