Without information about past timesteps, our method resolves intersections on cloth with boundaries. Using a global intersection analysis, we determine interpenetrating regions of the cloth.We analyze the possible intersection paths on 2D manifolds with boundaries and present a classification of intersection paths according to the position of their endpoints and the number of degenerated vertices on the path. Radial basis function (RBF) fitting is used to extrapolate correspondence information available on the intersection paths to the surrounding cloth. Attractive forces between corresponding points in the interpenetrating cloth region resolve the intersections. Our method can be applied as a preprocessing step to ensure that modeling results are suitable for animation. It can also be used during animation to correct intersections introduced by constraints.
