Multi-layered deformable surfaces for virtual clothing

We propose a positional constraint method to solve the multilayered deformable surface problem based on a master-slave scheme. This allows two or more deformable surfaces to be attached together in any orientation relative to each other for the purpose of modeling cloth attachments and multilayered clothing. The method does not require the mesh resolution of the deformable surfaces to be the same or the matching of anchor points between layers. After the attachment process, the surfaces are treated as a multilayered surface. However, this surface contains non-manifold features. We introduce a technique for preventing self-intersection of the non-manifold features. We demonstrate the stability of this method by performing several experiments with high surface complexity and a large number of colliding feature pairs. Interactive rates can easily be achieved for multilayered surfaces with an appropriate discretization level of triangles.
