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。该文将地形生成技术概括为三维地形简化技术、大规模地形数据的动态调度与地形简化相结合的处理技术和地形纹理数据的组织与应用技术等三大类,并分别介绍了这三类技术的相关理论和方法。
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 paper generalizes terrain generation techniques into three kinds: technique of three-dimensional terrain simplification,technique of combining of terrain simplification and dynamically schedule of large scale terrain data, technique of organization and application of terrain texture data,and introduces the relevant theories and methods respectively.
