【摘要】 本文首先分析了边界B样条拟合离散化误差的原因，在此基础上提出了边界拟合中的走样改进算法。论文简要介绍了两种反走样算法，详细阐述了反走样改进算法实现的具体过程及算法实现的数学基础。实际结果证明了改进算法的有效性。更多还原

【Abstract】 In this paper the reasons of deviations occurred in the boundary B-spline fit are analyzed at first. The angialiasing algorithm is put forward to make the boundary more smooth. Two algorighms of antialiasing are introduced bridfly. The concrete steps and procedures of the impuoved antialising algorithm are discussed in detail. The mathematical principle of the algorithm is also presented here. The experimental results shown the effectiveness of the improved algorithm.更多还原
