摘　　要：三维地形是虚拟自然环境中不可缺少的因素,也是虚拟仿真领域中视景系统的重要组成部分。近几年来,研究者们发展出了多种付诸实用的地形简化方法。根据应用目的的不同,使用的方法也多种多样,各有优点和不足之处。通过对现有三维地形简化算法的分析,总结了各类算法的优缺点,并着重介绍了典型的地形简化算法,并分析了三维地形简化算法发展趋势。Three-dimensional terrain is one of important factors of the natural scenes in virtual environment. It is also a significant composition of view system in virtual simulation field. The theory of three-dimensional terrain simplification was presented in eighties, and in recent years, the researcher has proposed many terrain simplification methods. According to various applications, the methods are different, and they have different advantages and disadvantages. The paper presents the terrain simplification methods, introduces typical terrain simplification methods, and analyzes the developing trend of the three-dimensional terrain simplification.
