    abstract     = "In this paper, we propose a pose editing and animation method for triangulated surfaces based on a user controlled partitioning of the model into deformable parts and rigid parts which are denoted handles.  

In our pose editing system, the user can sculpt a set of poses simply by
transforming the handles for each pose. Using Laplacian editing, the
deformable parts are deformed to match the handles. In our animation system the user can constrain one or several handles in order to define a new pose. New poses are interpolated from the examples poses, by solving a small non-linear optimization problem in order to obtain
the interpolation weights.

While the system can be used simply for building poses, it is also an
animation system. The user can specify a path for a given constraint and the model is animated correspondingly."
