PROBLEM TO BE SOLVED: To obtain an animation generator which obtains a flow of animation easy to appreciate even in the case that a partial specific part of a three- dimensional object repeats a small movement at the time of moving a virtual camera in accordance with the object. SOLUTION: An animation generation part 3 is provided with a projection attribute change part 6 which designates a model of a specific three-dimensional object, which is to be mainly a projection object, out of models of plural three- dimensional objects and obtains the centroid of the designated model of the three-dimensional object and temporally changes it so that it may occupy the center of a two-dimensional image of animation projected at each plotting time. A representative point of not a partial part of the model of the object but the entire model is set in the direction, to which the virtual camera is turned, to average movements of individual parts, and excessive shake of the direction of the virtual camera is prevented to obtain a smooth camera work.
