Motion data to be inserted between two different object actions that include a rotating action and are to be successively performed are generated so that the two actions are smoothly connected. Respective elements d required to define a transitional motion action are calculated from the respective frames after the end point of the former motion and before the start point of the latter motion. As for the three-dimensional rotation R(t) that defines the posture in each frame, independent linear values rx(t), ry(t), and rz(t) are calculated as values approximating the three-dimensional rotation R(t) by using exponential maps. The velocity components of the respective elements d are determined, and the largest value of the absolute values of the velocity components in each of the post-end frames and the pre-start frames is extracted as an interpolating velocity v(t). The respective elements d(t) in each of blended transitional motion frames can be determined by applying the Poisson's equation to the extracted interpolating velocity v(t). |
