Construction and Analysis of Binary Subdivision Schemes for Curves and Surfaces Originated from Chaikin Points

Figure 10

Solid lines represent initial polygons while dash lines represent limit curves obtained by subdivision schemes proposed ((a) and (c)) by us and ((b) and (d)) by Romani.

(a) Proposed uniform scheme ,

(b) Uniform Romani’s scheme ,

(c) Nonuniform proposed scheme ,

(d) Nonuniform Romani’s scheme ,
