针对射频仿真中的场景可视化问题,研究了一种基于OpenGL的导弹作战三维视景仿真方法。讨论了模型建立、纹理映射、粒子系统等OpenGL编程的几项关键技术,建立了导弹、发射车、飞机的三维模型,制作了天空、云彩、尾焰等特殊效果。利用定时器和双缓冲技术完成连续动画效果,并添加了同步背景音乐,在动画驱动的同时还可人机交互。仿真结果表明此方法实时性好,真实性、可操作性较强,具有较好的工程应用价值。

Aiming at the visualization of the scenes in radio frequency simulation, one 3D scene simulation method is studyed. It is based on OpenGL and simulates the missile's battle. The article have discussed several key technologies in OpenGL, such as modeling, texture mapping, and particle system, and builded the three-dimensional models of the missile, launch vehicle and aircraft. The special effects of the sky, clouds and the tail flame were also established with that. The continuous animation effects are realized by using timer and double-buffering, and the synchronous background music is added. While implementing animation-driven process, experimenter can work with the human computer interaction platform as well. The computer simulation indicate the method have advantage of real-time, factuality and manipulation, and have a good engineering application.
