Another algorithm is based on pixels : sample many points along the curve, round them to the nearest integer and set each pixel the computed point falls in. although this algorithm uses integer arithmetic, it provides the smooth curve possible at the expense of computation time as many points have to be computed to ensure that no gaps are created along the curve. furthermore these two algorithms we mentioned above is appropriate for low degree parametric curves, for high degree parametric curves, we usually approach them by using low degree rational parametric curves, the generating curve ' s fairness property is not very good
我們知道當節點矢量的兩端節點均為k重節點且無內節點時， b樣條基函數退化為bemstein多項式，因此該生成演算法還可推廣到b能ier曲線中，具有廣泛的應用價值、同樣地，在cad和cagd中，有理b樣條曲線，特別是非均勻有理b樣條曲線（ nurbs ）已經成為曲線曲面設計中最廣為流行的技術，然而對這些曲線目前也尚無很好的曲線生成演算法，因此有理b樣條曲線的生成演算法無疑有著更重要的意義 -
