An Improved Friction Model for Cloth Simulation

Friction is a complex phenomenon that resists tangential motion between two contacting objects. In computer graphics, existing cloth simulation methods have typically used a Coulomb model for friction, both static and kinetic. However, the Coulomb model is limited since it intends to capture fundamental frictional phenomena. Many observed friction effects such as stiction, Stribeck friction, viscous friction and the stick-slip phenomenon are not modelled by it. This paper describes an improved physically based friction model for simulating such effects, extending the Coulomb model.We show that including these additional effects is relatively straightforward. Results and comparisons with a pure Coulomb model are provided to demonstrate the capability and features of the improved model.
