The air combat visual has a characteristic that the eyeable airspace is big ( more than 20 kilometers ) but target is small ( all fighter plane is small in 30 meters ) 摘要空战仿真视景具有可见空域大（ 20公里以上）而靶标小（战机均小于30米）的特点。

The eyeable ballistic simulation is completed after reading the ballistic data . the landform in the eyeable scene is formable by use of algorithms for generating fractal terrain 读取数据并形成可视化弹道仿真，建立的可视化场景中运用了当前较新的分形算法产生地形。
