| Abstract: | In order to enlarge the extension of free form surface,the extension of Wang-Ball surface over triangle domain is provided by introducing banding shape parameter in this paper. By changing the value of the shape parameter,the shape of the new surface can be adjusted,the shape parameter is endowed the property of geometry. The results show that the larger is the parameter,the more approaches the surface to the control net. |
