Elasticity-Inspired Deformers for Character Articulation

We present a new automatic skinning technique which mimics the quality of nonlinear elastic simulation at speed comparable to linear blend skinning.

Simulation of complex nonlinear elastic bodies using lattice deformers

We present a new approach for simulating nonlinear elastic bodies using lattice deformers. Our method accommodates arbitrary nonlinear materials, including anisotropic models of muscles, and supports arbitrary degrees of incompressibility. Our discretization treats models at a sub-voxel accuracy, while requiring a cost commensurate with simpler, merely voxel-accurate techniques.

RigMesh: Automatic Rigging for Part-Based Shape Modeling and Deformation

RigMesh is a sketch-based modeling tool for the creation and editing of articulated 3D shapes. A skeleton is generated from a silhouette sketch, and a valid rig is maintained throughout the modeling process; skeleton, skin weights, and a closed surface mesh are computed in real-time.

Smooth Skinning Decomposition with Rigid Bones - Picture

Smooth Skinning Decomposition with Rigid Bones

This paper introduces the Smooth Skinning Decomposition with Rigid Bones (SSDR) that can effectively approximate the skin deformation of nearly articulated models as well as highly deformable models by a low number of rigid bones and a sparse, convex bone-vertex weight map.
