Advanced Physical Face Rigging for Enhanced Facial Animation Control
This work presents a state-of-the-art approach to physical face rigging, utilizing data-driven methods to simplify the generation of diverse face models through an intuitive interface. The proposed formulation employs physical-based deformation techniques, including spring-mass systems and tetrahedral numerics, to create realistic facial expressions. Demonstrations of the animation control interface showcase the effectiveness of this method. Future goals include integrating a more user-friendly GUI for boundary settings and coefficients to enhance video-driven facial animations.

Motivation • Help users more easily generate varieties of face models with simpler interface.
Physical based deformation • Spring Mesh Boundary Apply Mass & Force Tetrahedralize
Numerics • is the expression generated by this method • is the ith blend shape generated by expression cloning • is the expression generate by spring mesh
System Demonstrations Interface to control the animation Face deformation system
What I accomplished • Spring Mesh based deformation • Expression Cloning • The optimization formulation • Parameter based interface
Summary and Future work • This term I learned some technologies which I adopted in my project: • Spring-mass system • Integration methods • Mesh deformation • In the future, I hope to implement more intuitive Gui to set boundary and deform coefficient and embed it into a video driven facial animation system.
