Abstract: In order to change the positions of a plurality of nodes that constitute a line or a surface, following steps are executed: storing in a storage device data of a normal for each node; changing the position of each node and storing the position information into the storage device by (1) defining a virtual elastic member connected to each node in a direction of the normal of each node, and (2) stretching or shrinking the elastic members in the direction of each normal so as to balance each elastic member; and repeating the storing step and the changing step until a predetermined condition has been satisfied. As a result, a smooth curve or smooth surface is generated.
