Bending Modeling Based on the Mean Curvature for Cloth Simulation

The presentation of cloth bending properties plays a key role in cloth animation research. This paper proposed the approximate nonlinear bending model based on local geometric information. In the dynamic simulation, cloth was divided into several regions according to mean curvature of surface and bending force was updated according to the changes of the mean curvature in each region. The calculation of bending force was simple and accurate with the proposed model. Experimental results show that wrinkles and folds generated in a natural way and the efficiency of cloth simulation is improved.
