Description

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. SM (Shape Matching)2),6) 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 of not preserving its volume. We propose a novel volume-preserving deformation method based on LSM. Our method can achieve more elastic-like motions than the original LSM while keeping fast and robust computations. And, We show an adaptableness for arvitrarily distributed points, as well as latticed points.
