integer arithmetic meaning in English
整数运算
Examples
- 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
我们知道当节点矢量的两端节点均为k重节点且无内节点时， b样条基函数退化为bemstein多项式，因此该生成算法还可推广到b能ier曲线中，具有广泛的应用价值、同样地，在cad和cagd中，有理b样条曲线，特别是非均匀有理b样条曲线( nurbs )已经成为曲线曲面设计中最广为流行的技术，然而对这些曲线目前也尚无很好的曲线生成算法，因此有理b样条曲线的生成算法无疑有着更重要的意义 - We compare the algorithms in the present work with the traditional algorithms , and can come to the conclusion that the former is more efficient . in the work we discuss the point - by - point algorithms of implicit curve and surface systematically , introduce the general and extended algorithms of line - drawing , and have these algoritms improved . an all - integer arithmetic algorithm is also introduced , we improve the algorithm and extend it to surface
介绍了隐式曲线的整数型逐点生成算法，将它进行改进，扩大了它的适用范围；并将这个算法推广到隐式曲面，把隐式曲面的绘制问题转化为隐式曲线的绘制问题，提出了一个对隐式曲面有效的逐点生成算法。
