| Abstract: | This paper presents the general transforming matrix between new vertices and old vertices for splitting equidistributionally the B-Spline curve segment. The result obtaind in this paper extends and improves the subdivision prin- ciple presented by Lane,J.M.and Riesenfeld,R.F.in 1980 and by Shi Fazhong in 1988 in different forms,and has a wide generality.They have a widesprend practial value in computer aided geometric design and computer graphics. |
