In animations and virtual reality, contact models have been widely used in many areas like rigid body collision and soft body deformation. Contact happens on a locally optimal configuration which forms Vertex/Face (VF) and Vertex/Vertex (VV) contacts. Several optimal methods have been developed to this, such as Continuous Collision Detection (CCD) and Linear Complementarity Problem (LCP) with Gauss-Seidel iterative solver [Kaufman et al. 2008].
