The influence parameters /spl beta//sub 1 / and /spl beta//sub 2 / have on bibeta spline curved surface
This paper discusses how Beta spline curve with geometric continuity is influenced by the change of parameters beta1 and beta2, offers the range of parameters beta1 and beta2 and presents the algorithm principles of bibeta spline curved surface that is controlled by double parameters. Based on all above, a freedom surface modeling system (FSMS) is designed and some examples are verified and analyzed
