Robust treatment of complex collisions is a challenging problem in cloth simulation. We present a fail-safe that cancels impact but not sliding motion. This reduces artificial dissipation considerably. We equip the proposed fail-safe with an approximation of Coulomb friction, allowing finer control of sliding dissipation.
