A tool for inbetweening is provided, wherein inbetween frames are at least partly computer generated by analyzing elements of key frames to identify strokes, determining corresponding stroke pairs, computing a continuous stroke motion for each stroke pair, defined by a carrier defined by endpoints of the two strokes and, for mutual endpoints, adjusting the continuous stroke motion of the meeting strokes such that the adjustment results in the continuous stroke motion coinciding at the mutual endpoint such that the mutual endpoint would follow the same path and deforming the stroke as it is moved by the stroke motion, wherein the deformation is a weighted combination of deformations, each reconstructed using shape descriptors that are interpolated from the shape descriptors of the corresponding samples on the key frames, wherein the shape descriptors are computed from neighboring sample points in the cyclic order of samples along the stroke.
