Transferring existing mesh deformation from one character to another
is a simple way to accelerate the laborious process of mesh
animation. In many cases, it is useful to preserve the semantic characteristics
of the motion instead of its literal deformation. For example,
when applying the walking motion of a human to a flamingo,
the knees should bend in the opposite direction. Semantic deformation
transfer accomplishes this task with a shape space that enables
interpolation and projection with standard linear algebra. Given
several example mesh pairs, semantic deformation transfer infers
a correspondence between the shape spaces of the two characters.
This enables automatic transfer of new poses and animations.
