In nature, many things are complex in shape and movement. Realistic representation of human beings and animals is made using computer graphics, but there are few researches on the representation of human hair. We have already proposed a stochastic model of movements of threads to try to represent thread-like objects, including human hair, blown by the wind. For such cases, an appropriate way of choosing parameters like the wind direction and strength was not known. We now propose a method using the solution of the two-dimensional potential flow equation in order to give values to these parameters.
