A family of Said-Bézier type generalized Ball(SBGB) bases and surfaces with a parameter H over triangular domain is introducermediate surfaces.To convert different bases and surfaces,the dual functionals of bases are presented.As an application of dual functionals,the subdivision formulas for surfaces are established.
