  We introduce Fat Pad cages for posing facial meshes. It combines cage
representation and facial anatomical elements, and enables users with no
artistic skill to quickly sketch realistic facial expressions. The model relies
on one or several cage(s) that deform(s) the mesh following the human fat pads
map. We propose a new function to filter Green Coordinates using geodesic
distances preventing global deformation while ensuring smooth deformations at
the borders. Lips, nostrils and eyelids are processed slightly differently to
allow folding up and opening. Cages are automatically created and fit any new
unknown facial mesh. To validate our approach, we present a user study
comparing our Fat Pad cages to regular Green Coordinates. Results show that Fat
Pad cages bring a significant improvement in reproducing existing facial
expressions.
