  In animation, style can be considered as a distinctive layer over the content
of a motion, allowing a character to achieve the same gesture in various ways.
Editing existing animation to modify the style while keeping the same content
is an interesting task, which can facilitate the re-use of animation data and
cut down on production time. Existing animation edition methods either work
directly on the motion data, providing precise but tedious tools, or manipulate
semantic style categories, taking control away from the user. As a middle
ground, we propose a new character motion edition paradigm allowing
higher-level manipulations without sacrificing controllability. We describe the
concept of pose metrics, objective value functions which can be used to edit
animation, leaving the style interpretation up to the user. We then propose an
edition pipeline to edit animation data using pose metrics.
