摘　　要：介绍了利用粒子系统方法模拟动态自然景物的基本步骤。应用了VegaPrime实时视景仿真软件中的粒子系统,通过设置粒子系统的颜色、亮度、透明度、形状、纹理、大小、速度和位置,逼真的模拟了火焰和烟雾的特效。通过将火焰粒子系统在发射坐标系中的速度转换到场景坐标系中,实现了火焰随着发射装置的随动。The basic procedure to simulate dynamic natural objects with particle system method was introduced. The special effect of the flame and smog was simulated perfectly by setting the color,brightness,transparency,shape,texture,size,velocity and position of the particle system in Vega Prime real time scene simulation. The movement of flame with the launching equipment was achieved by transforming the velocity of launching coordinate system to scene coordinate system.
