摘　　要：针对空对空作战仿真过程直观化以及仿真结果更有利于分析的需求,建立了一个具有沉浸感和交互作用能力的空战三维视景仿真环境。首先,利用建模软件Creator进行了飞机、导弹的三维实体模型和作战场景建模。然后,在空战飞行仿真系统之上,基于Vega Prime平台构建仿真环境的三维视景子系统,实时动态再现空战飞行和打击的全过程,重点研究了实现空战视景仿真的几项关键技术和实现方法,包括飞机舱内视点下的平显系统显示;基于MFC开发视景子系统的程序驱动过程;基于粒子系统的战场环境特效处理技术;以及从舱内以及舱外不同方位进行观察的视点变换。最后给出了空战视景仿真的实施效果,结果表明该系统较好地满足了空战虚拟战场三维演示的需求。Considering the requirements of air-to-air combat simulation of getting direct vision and easy analysis for simulation results, a 3D simulation environment of air combat with good immersion and interaction is established. First, models of 3D entities of plane/missile and combat field are established by using Creator. Then on the basis of air combat flight simulation system, 3D scene subsystem of simulation environment for air combat is established on Vega Prime platform, reappearing the real-time flight and attack process of air combat. Several key technologies and realization methods of air combat visual simulation are mainly studied, including HUD display at the inside cabin view, MFC-based program drive process to develop visual subsystem, disposal technology for special effects of environment based on particle system and viewpoint transform from different directions outside cabin. Finally, effects of the air combat visual simulation are given, the results of which proved that this system meet the need of 3D display for air combat virtual combat field preferably.
