Animation of stochastic motion of 3-D cloth objects

Abstract This paper presents a physically-based aerodynamic force model for the realistic animation of a three-dimensional cloth object, such as a skirt. The model is based on the theory of low speed aerodynamics with some modifications to model the unsteady movement of a 3-D cloth object in air flow. The consideration of the solid object in the vicinity of the cloth, the porosity of the cloth and the collision detection of the cloth with other objects and with itself are also included. To achieve more realistic animation, a stochastic wind model has been proposed to model the free stream air flow. Realistic animation results of a skirt moving in air flow have been obtained by applying these models.
