Abstract:
1. A computer graphics (CG) animation apparatus for displaying a character image, the computer graphics animation apparatus comprising: a structure storing unit operable to store structure data showing a hierarchical structure for a plurality of character elements that make up the character image; a table storing unit operable to store a group table showing a plurality of groups that each include some of the character elements; a motion data storing unit operable to store motion data representing motions, each of which is associated with one of the plurality of groups; an animation control unit operable to specify the motion data, the group table, and the structure data; and a state calculating unit operable to calculate shape data representing change in the character image over time in accordance with the motion data, the group table, and the structure data specified by the animation control unit, wherein for each of the plurality of groups, the motion data storing unit stores a plurality of sets of motion data representing a plurality of motions associated with a group, one of the motions being a basic motion, and the animation control unit also compulsorily specifies, for each of the plurality of groups, a set of motion data representing a basic motion, and then replaces the specified group table with another group table after synchronizing the plurality of groups.
