Despite the
tremendous amount of artistry, skill, and time dedicated to crafting
animations, only few special-purpose techniques exist to help with reuse. Motion retargeting, for example, conforms
motions of rigid skeletons, but stalls when enforcing the laws of physics or
when transforming the motion of deformable shapes. Until recently, physically valid retargeting relied
on simplification to eliminate degrees of freedom or to reduce the order of
dynamics equations. These
simplifications are not necessary as demonstrated with numerical procedures for
retargeting ballistic motions of a full human figure with many degrees of
freedom. Similar approach could enable
reanimation of meshes with non-skeletal deformations or without an obvious skeletal
structure. Deformation transfer is the
first step to developing such a system.
It applies the deformation exhibited by a source triangle mesh onto a
different target mesh without requiring them to share the same connectivity or
to have an identical number of triangles and vertices.
