circular arc

基本解释

Sometimes programmers erroneously force users to trace a circular arc with their mouse, which can be quite challenging .
有时，程序员错误地强迫使用者用鼠标来描圆弧，这是相当有难度的。
Tangential continuity [C1 or G1] is the next level, defined by a circular arc creating a relatively smooth transition between these surfaces.
相切（Tangential）连续性[C1 or G1]则是下一个层次，指的是建立一个连接这些表面间的平滑的圆弧过渡。
This draws a circular arc at (150, 150) on the page (relative to the bottom-left corner), of radius 10, from angle 0 to angle 360, or a full circle.
这段代码将在页面的 (150, 150) 位置（相对于左下角）绘制一个半径为 10 的圆圈，从 0 度到 360 度（即完整的圆圈）。

圆弧
Furthermore,some circular arc spline curves which have C0 or GC1 continuity are constructed.
本文进一步构造了具有一定光滑性质的圆弧样条曲线。
