摘　　要：虚拟战场中不规则物体的实时显示能够增强人们在虚拟环境中的沉浸感。文中论述了在实时性要求很高的某型车辆视景仿真系统中,应用粒子系统方法构建简单模型实现爆炸效果的具体步骤,并提出了提高算法实时性的技巧,此方法已应用于仿真系统中,在一般配置的微机上实现20f/s的刷新率,模拟效果逼真,同时满足了系统实时性。The real-time simulation of dynamic and irregular objects can increase the immersion in the virtual environment. It proposed an approach of particle system to animate the explosion in the car vision simulation system which the real-time rendering is demanded, then gives some techniques to improve the simulation speed. This approach has been implemented in the simulation system and realized the refresh rate of 20f/s in the common computer. The result shows the vivid appearance, at the same time it meets the real-time requirement of the system.
