Abstract

Articulated body animation with smooth skin deformation is an important topic in computer graphics. This paper presents a pipeline that extends articulated body deformation to the volume graphics domain. The pipeline consists of in-vivo volume scans, kinematic joint estimation, volumetric joint weight computation, soft-tissue volume deformation, and direct volume rendering. The result is a fully articulated body volume driven by intuitive joint control that respects rigid deformation of the bone structures and produces smooth deformations of both the skin surface and the interior soft tissue regions.
