Erratum to: Conversion and evaluation for two types of parametric surface constructed by NTP bases [Comput. Math. Appl. 49(2) (2005) 321329]
It is pointed out by Jiang and Wang (2005)[1], that the conversion formula from Bernstein into DP bases is incorrect for all even degrees and the conversion formula from DP into Bernstein bases is incorrect for every degree. Thus, in this paper we give some notes, corrections and new proofs for the relationship between these two NTP bases.
