| 摘 要： | 给出了曲线（包括参数曲线、非参数曲线、极坐标曲线等）的像素级绘制的差分建模算法．在曲线的逐点生成过程中，只用到整数的加减法运算，运算量小，效率高．可推广到多项式曲面．

| Abstract: | A pixel level difference algorithm of generating curve is present. In its process of generating the curve point by point, only integer additive and subtractive operations are involved,so it is quite efficient. The approach can be generalized in polynomial parametric surfaces. |
