Space Deformation for Character Deformation using Multi-Domain Smooth Embedding

Abstract

We propose a novel space deformation method based on domain-decomposition to animate character skin. The method supports smoothness and local controllability of deformations, and can achieve interactive interpolating rates. Given a character, we partition it into multiple domains according to skinning weights, and attach each to a linear system, without seam artifacts. Examples are presented for articulated deformable characters with localized changes in deformation of each near-rigid body part. An application example is provided by usage in deformation energies, known to offer preservation of shape and volumetric features.
