Paper [ 76 ] provides a integer algorithm for rasterizing free curves , we need change the curve form to implicit function form , then use curve ' s positive - negative property to draw , but we ca n ' t use this algorithm when curve ' s degree is higher than 3 and this algorithm ca n ' t avoid using multiplication ; paper [ 77 ] provides a new generating algorithm , this algorithm can draw bezier very well , but for b - spline curve , we need use convert them into bernstein base form . because this process spends a lot of time , this algorithm has not a good speed and effect for rendering rational b - spline curve 现在经常采用的算法也是基于几何的算法(即线式生成算法)和基于像素的算法(点式生成算法) ;文献78 ]提供了一种有理参数曲线的快速逐点生成算法，该算法对有理b吮ier曲线的绘制，能起到很好的作用，但是对于有理b样条曲线，必须先通过多项式的代数基与bemstein基间的变换矩阵，把原式用bemstein基表示，这一过程由于计算量大，降低了曲线生成的速度和效率
