Abstract:
We discuss a method for creating animations that allows the animator
to sketch an animation by setting a small number of keyframes
on a fraction of the possible degrees of freedom. Motion capture
data is then used to enhance the animation. Detail is added to degrees
of freedom that were keyframed, a process we call texturing.
Degrees of freedom that were not keyframed are synthesized. The
method takes advantage of the fact that joint motions of an articulated
figure are often correlated, so that given an incomplete data
set, the missing degrees of freedom can be predicted from those that
are present.
