Intuitive Modeling of Folds and Wrinkles in a Cloth Simulation

Cloth modeling and animation aiming high realistic visual effects are very complex processes. It may involve the formulation of a physically-based model, collision detection and response techniques, and a time-consuming integration numerical solver. This is because cloth presents a very peculiar behavior. It bends easily, while hardly stretches. Folds naturally appear and disappear, yielding diverse wrinkles and buckles, which are recognized to be fundamental for realistic simulations. Modeling these phenomena, and yet, controlling the aspect of folds without resorting to artificial forces is a field that still needs improvements. In this paper we analyze the interdependence of the parameters in the deformable surface model proposed by Melo and propose a geometry oriented control that is suitable for generating a large variety of folds and wrinkles.
