【摘要】 由于椭圆曲线在加工、求交中有困难,本文提出利用双圆弧拟合,将椭圆曲线转换为多段圆弧曲线,文中阐述了用四段、八段、十二段以至更多段圆弧代替椭圆的图形处理方法及图形精确度讨论,最后提供了各段圆弧数据的程序设计思想。更多还原

【Abstract】 Owing to the fact that there are difficulties in machining and intersecting ellipse curves,this paper develops a techniques transforming ellips curves into multi -arcs by biarc fitting. According to the proposed method of graphical processing, an ellipse can be approximated by 4,8,12 or more arcs. And ,the fitting precision of graphs is also discussed. Finally the paper provides readers with soft ware diagram which can be employed to find the data values of various arcs.更多还原
