Data processing apparatus and processing method and medium for electronic games

A data processing apparatus for positioning a game character on a display, said apparatus comprising:

• a game character model, including a reference polygon and component polygons that are separated from the reference polygon, wherein no other polygons are included between said reference polygon and said component polygons;
• a motion data table for pre-storing motion data for executing a movement of the game character model, wherein motion data includes distance data and angle data defining predetermined motions of the game character model, and wherein the motion data is character data including a joint area;
• and
• a processor, wherein the processor computes the reference polygon at each of a plurality of trigger times corresponding to an occurrence of a predetermined scene based on a position information of said reference polygon and the motion data, places the reference polygon in a three-dimensional space, and directly places said component polygons for said reference polygon in the three-dimensional space based on the position information of said reference polygon using the motion data without computing any other component polygons.
