摘要： 本文提出十种圆弧直接剪取算法,它适用于如:CIRCLE(x,y,r,α,β)的画圆语句,这里x,y为圆心座标,r是半径,α和β分别为圆弧起始角和终止角的弧度值。
Abstract: In this paper, a direct algorithm for circle clipping is proposed. It is suitable for statements such as CIRCLE (x, y, r, α, β). Here x, y are the coordinates of the centre of the circle. r is the radius. α and β are the radian values of the beginning angle and ending angle respectively.
