Abstract

Motion transition of virtual human is usually used for changing from one motion to another, which is one of the most important motion editing methods for virtual human motion capture data reuse. In this paper, we present a solution to connect virtual human motion clips smoothly by using bezier quaternion curve. Four control points are used to determine the shape of the bezier quaternion curve and De Casteljau’s algorithm is for calculating interpolation points. Slerp (the abbreviation of quaternion spherical linear interpolation) is chosen as the interpolation method. As a result, realistic and real-time human motion transition is achieved, as experimentally demonstrated with the walking and running motion sequences.
