三维大地形模型的生成与管理方法研究

Research on Generating and Managing 3D Large Terrain Model

以虚拟战场环境为背景,针对大地形可视化中的特殊要求,介绍了三维大地形模型的生成方法和步骤,阐述了地理数据格式的转化方法和人文特征的读取方法与显示途径。实验结果证明该方法可以有效地应用于三维大地形模型的生成与管理,并为最终建立大范围的虚拟战场环境提供基础。

It is introduced the methods and steps for generating the large scale terrain models under the context of virtual battlefield environments. And the methods for transforming the geographic data format and reading and presenting the civil feature data are discussed as well. The experimental results show that the methods we presented are efficient to create and manage a 3D large terrain model. So these methods can provide the foundations for constructing the virtual battlefield environments.
