CGF地形数据库格式研究

Research on CGF Terrain Database Format

CGF地形数据库对于开发高质量的CGF仿真系统 ,提军事训练效果起着至关重要的作用。该文在对CGF需求进行分析的基础上 ,确定CGF地形数据库中包括地形表面、物理特征、抽象特征和线性拓扑在内的基本格式。通过分析仿真需求 ,选择了适合于CGF地形数据库的GCS坐标系统。

CGF terrain database is one of the key elements for developing CGF simulation systems and improving the effect of the training. By the requirements analysis of CGF, this paper determines the basic formats of the CGF terrain database including terrain skin, physical features, abstract features, and linear topology. We also choose the appropriate coordinate representation in CGF terrain database by analyzing the simulation requirements.
