| 摘 要： | 为了提高曲线生成算法的速度，讨论了如何选择最佳的步长，使曲线前进的幅度在不超过一个象素的前提下，选择尽量大的步长．为了进一步提高算法的速度，采用了双步逐点曲线生成算法，设计使用Visual C 6．0为工具，并以曲线方程为例实现了该算法．

| Abstract: | The paper mainly describes the improved algorithm for rasterizing parametric curve.To speed up the arithmetic of the drawing of the curve, the paper also discusses the choice of the best step length to choose the biggest step length on the condition that the progress range is less than one plex. To speed up the arithmetic further, the paper take the arithmetic of double step form of the curve by point to point. This design has used the Visual C++6.0 and take example for the rasterizing parametric curve to complete the program. |
