In recent years, computer animation based on physical fluid simulation is becoming a hot research domain. In this paper, physics-based methods are used to realize the smog animation simulation combining computational fluid dynamics and computer graphics. The equations of the shape controlling force based on the free movement equations are increased in the physical model of smog, so as to achieve the effective shape control. The physical model of smog is expressed by equation as classic Navier-Stocks equation, and then the authors get the three-dimensional density field data.
