Surface deformations based on physically-based simulations are used to represent elastic motions such as human skins or clothes in the field of 3DCG applications. LSM (Lattice Shape Matching) [Rivers and James 2007] has particularly attracted attention as a fast and robust method which achieves elastic-like motions. However, the original LSM deformation method generates far from realistic motions especially when stretching an object, because volume is not preserved. We propose a novel volume-preserving deformation method based on LSM. Our method can achieve more elastic-like motions than the original LSM while maintaining fast and robust computations.
