Abstract
A method, apparatus, and software product interpolates inbetween shapes of a two- or three-dimensional geometric model between a sequence of key poses of the model using a new type of parametric curve with shape parameters for providing independent control over the properties of the curve. The shape parameters provide the animator with full control over the behavior of the interpolated shapes between one key pose to the next. More specifically, these shape parameters independently control the direction, absolute magnitudes, and relative magnitudes of the incoming and outgoing tangent vectors at each key pose.
