Evaluation of motion retargeting using spacetime constraints
Summary
This thesis report describes the evaluation of the retargeting method “Retargetting Motion to New
Characters” as introduced by Gleicher. Our description of the method shows more details than the
original paper does. This report also grants more background information about differentiation a
constraint function, using either divided differentiation or automatic differentiation. Furthermore
the for the interpolation method, a B-spline, is explained more extensively. Explaining the range
of influence of B-spline control points and calculating a point on the B-spline locally without
evaluating the whole spline. Finally experiment have been executed on our own implementation
of this method. The experiments evaluate the method on its performance with different kinds of
constraints, different motions and different scalings. The resulting motions of those experiments
are inspected visually on quality.
