Abstract in different language: Real-time simulation of physically realistic complex dust behavior is very useful in computer simulation, training, education, art, advertising, and entertainment. There is no successful model for realistic dust behaviors generated by a traveling vehicle. In this paper, we use particle systems and behavioral simulation techniques to simulate these dust behaviors in real-time. First we analyze the forces and factors which affect the dust generation and the behaviors after dust particles are generated. Then we construct physically-based empirical models to generate dust particles and control the behaviors accordingly. After that, we further simplify the numerical calculations by dividing the dust behaviors into three stages, and establishing simplified particle system models for each stages. In addition, we discuss the methods to simulate the behaviors in a networked virtual environment. Our major contribution includes analyzing dust behaviors in detail, constructing physically-based empirical models that correlate the behaviors to the dust generating forces and other factors, and that achieve simulations in a networked virtual environment.
