Motion adaptation by dynamical Distance Geometry
Distance-based motion retargeting leads to the formulation of a dynamical Distance Geometry Problem (dynDGP) where the involved distances represent at the same time the morphology of the animated character, together with its motion. The use of relative distances becomes fundamental when, because of a modification on the morphology of the character, self contacts (represented in this context by distances having value near 0) may disappear from the motion, or unwanted new contacts may be introduced. We revisit a recently proposed approach to human motion retargeting that is essentially based on distance information. This revisited approach is able to avoid some artifacts that were observed in the preliminary experiments performed in the context of distance geometry.
