Abstract. Distance-based motion adaptation (also referred to as ``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 with distances having value near to~0) may disappear from the motion, or unwanted new contacts may be introduced. We revisit a recently proposed approach to human motion adaptation that is essentially based on distance information.
