A New Paradigm to Design a Class of Combined Ternary Subdivision Schemes
Figure 6
Red bullets show the initial control points. Black solid lines are the initial control polygon. Coloured lines show curves fitted by our subdivision scheme after two refinement steps. (a) 4-point combined scheme ; (b) 4-point combined scheme ; (c) 6-point combined scheme ; and (d) 6-point combined scheme .
