Abstract
An object incorporated in image data is formed with a plurality of polygons. An object table defines each polygon by means of coordinates at an apex in a view coordinate system and the sound generated from the polygon. The sound source processor unit controls sound to be generated from each polygon according to the position and direction of the polygon when the object is viewed from a viewpoint.
