Abstract
Animation creating method for panting regions inside a polygon and/or creating polylines constituting a polygon without the shared use of vertices between shape elements. The method comprises the steps of: connecting a plurality of vertices by polylines to create a polygon A on a computer so as to store shape information about the polygon A into a data table; creating a polyline sequence B which either starts from or ends at one of the vertices of the polygon A; if the starting point of the polyline A coincides with a first vertex of the polygon A and if the end point of the polyline sequence B coincides with a second vertex of the polygon A, then dividing the polygon A by the polyline sequence B into polygons A1 and A2 while deleting the shape information about the polygon A from the data table and storing shape information about the polygons A1 and A2 into the data table; and displaying the resulting polygons on a display on the basis of the stored shape information.
