Motion graph approaches focus on the re-use of character
animation contained in a motion-capture repository by
connecting similar frames in the database with transitions.
Because the output animation of a motion graph comes directly
from the motion capture data except for the transitions,
the quality of the motion depends largely on the transition
points selected. In this paper, we investigate the comparison
metrics for choosing transition points, aiming at improving
the visual quality of animations generated using motion
graphs. Specifically, we focus on the weight assigned to
each body part, which reflects the relative significance
of the body part on the quality of the generated motion.
We introduce a novel weighting scheme, based on an
estimation of the character's dynamics, which assigns
weights for each body according to displaced mass and
simplified friction terms. To assess the quality of the
transitions selected by our proposed dynamics-based
metric, we compare its results to previous methods,
looking at both visual quality and quantitative analysis.
