Abstract

Energy damping is an important phenomenon to consider for the dynamic three-dimensional (3-D) simulation of warp and weft materials, since it has a great influence on the realism of cloth movement. This phenomenon can be generated either by friction between moving cloth and air, or by friction between the warp and the weft threads of fabric. Given a model for energy damping, model parameters are usually tuned by hand. In this paper, we present an experimental study using MOCAP system for acquiring precise 3-D trajectory data of real cloth in free fall movement. The contribution of this study is to measure experimentally the parameters of an energy-damping model for cloth using real 3-D trajectory data and evaluate their contribution for cloth simulation in the case of free fall movement. Validation of the viscosity parameters measurement is performed by the comparison between the real and the virtual trajectories (which are almost the same).
