| Abstract: | The limit of Bernstein-Bezier curve for periodic control nets is discussed in this paper. The Iimit of Bernstein-Bezier curve is the centroid of the control nets. The curve for fixed edge control nets reveals some interesting structures. L-system and Gray code are used to describe the periodic contral nets. |
