飞行仿真系统中三维地形的仿真实现

三维地形是飞行仿真系统中的重要组成部分,机场跑道作为飞机起飞降落过程中不可或缺的部分,其真实感直接影响着飞行仿真系统中地形的真实感.为了创建包含高真实感机场跑道的三维地形,在Unity下利用FlightGear中的地形数据、机场纹理数据及Google Maps纹理数据,通过动态创建地形网格和材质的方法,结合多线程技术,...

Realization of 3D Terrain Simulation in Flight Simulation System

3D terrain is an important part of flight simulation system. Airport runway is an indispensable part of the flight landing process, and its authenticity directly affects the authenticity of flight simulation system. In order to create 3D terrain with high realistic airport runway, the terrain data in FlightGear, airport texture data and Google Maps texture data are used under Unity. Through the method of dynamic creating terrain grid and material, combined with multithreading technology, the parallel creation of 3D terrain is realized. The experimental results show that the proposed method can quickly create 3D terrain including high realistic airport runway, and can be used to simulate 3D terrain in flight simulation system.
