Artist-Friendly Facial Animation Retargeting


This paper presents a novel facial animation retargeting system that is carefully designed to seamlessly integrate with a realistic production workflow. Our approach strives to provide a good starting point and convenient editing environment for follow-up editing.

Controlling Physics-based Characters using Soft Contacts


We investigate the impact of the deformable bodies on the control algorithms for physically simulated characters. We introduce a compact representation for an articulated character with deformable soft tissue and develop a practical system to simulate two-way coupling between rigid and deformable bodies in a robust and efficient manner.

Compression and Direct Manipulation of Complex Blendshape Models


A new method to compress large blendshapes data and to accelerate the animation processing is introduced. We also provide a direct manipulation approach to control many blendshapes intuitively.

Modal-Space Control for Articulated Characters


Our control algorithm for simulating an articulated character has the ability to make long-horizon plans at every time step by applying modal analysis on a time-varying linear dynamic system.

Stretchable and Twistable Bones for Skeletal Shape Deformation - Picture

Stretchable and Twistable Bones for Skeletal Shape Deformation


We propose a skinning deformation method that enables proper stretching and twisting along bones, without modifying the standard skin-skeleton metaphor of linear blend skinning (LBS) and its variants. We achieve this by introducing endpoint weights that have an intuitive geometric meaning and enrich the space of deformations reachable with LBS.
