This paper describes a dust modeling technique. An empirical method is used to visually simulate the effect of dust accumulation on object surfaces. The dust amount is first predicted based on the properties of the surfaces: the surface inclination and stickiness. This predicted amount is then adjusted according to some external factors: surface exposure to wind and scraping off by other objects. The calculated dust amount is finally perturbed by a noise function on rendering to give a fuzzy visual effect.
