Implicit Surface for Animation (zoom I)

Implicit Skinning

Use implicit surface representation to improve skinning deformation

1. Associate character parts with field function (HRBF)
2. Deform fields rigidly with bones
3. Project vertices onto isosurfaces

Improved shape around joints
Real-time
No-intersection \(\to\) contact surface
Shape of the contact can be controled

- Sharp, smooth contact, blending, ...
