绘制抗锯齿圆的一种好的算法是什么？ （已填充，但未填充。）

What's a good algorithm for drawing anti-aliased circles? (Filled and not filled.)

推荐答案

（在线算法闻名的）Bresenham也有一个循环算法。

Bresenham (of the line algorithm fame) also had a circle algorithm.

Xiaolin Wu修改了行算法以进行抗锯齿，同样对圆算法做了同样的处理。

Xiaolin Wu adapted the line algorithm for anti-aliasing, and likewise did the same to the circle algorithm.
