【摘要】 研究了一种基于OpenGL实现飞行器超低空追击/拦截三维可视化仿真系统的方法。首先利用3DSMAX软件构建大翼展无人机、武装直升机及机场的三维模型,并将其转换成OpenGL程序,从而降低了直接利用OpenGL构建复杂模型的难度,减小了建模的工作量。在实现三维动画驱动的同时还可进行人机交互控制,然后利用OpenGL建立飞行场景的三维模型,最终以三维动画仿真的方式从各个不同的角度来实现飞行器起飞、超低空追击/拦截、向敌机发射导弹和返航着陆的三维视景。结果表明,该三维仿真系统符合仿真系统三维化的发展趋势和虚拟现实的要求,具有较高的应用价值。更多还原

【Abstract】 How to realize 3D visualization simulation system of low altitude chase/interception based on open graphic library (OpenGL) is researched. Firstly, the 3D modeling of the big wingspan UAV, the arming helicopter and the aerodrome is achived by using 3DSMAX software. Then the model is transformed into OpenGL programs, thus overcoming the difficulty of construction complex model directly using OpenGL, and reducing the modeling workload. While implementing 3D driving, the alternative control between human and the computer is realized. The flight scenery is also established using OpenGL. Finally, from different points of view, 3D visual scenery of aircraft flying-off, low altitude chase/interception, shooting missile on the enemy aircraft, returned to the base and landing is obtained. The 3D simulation system has well applicational values and meets the needs of virtual reality.更多还原
