摘要
通常Bézier曲线求交研究侧重理论分析,所求出的交点一般不在已绘制的曲线上,不易用来对实际绘出的曲线作精确编辑,剪切时经常会出现空隙或毛头.提出一种与绘制Bézier曲线方法相吻合的Bézier曲线求交算法,称为Bézier折线求交法.所求出的交点可以用来对已绘制的Bézier曲线作精确编辑.该算法稳定、准确、快速.
Generally, the theory analysis is thought highly in researcn of intersection of Bézier curves.The intersection point from the theory analysis, generally not on the drawn curve, can't be used for trimming the drawn curve exactly, and the resulting trimmed curve may exhibit "gaps" and "overlaps" at their common point. A intersection algorithm of Bézier curves is presented which agrees with the way of drawing the curves, called intersection algorithm of Bézier broken lines. The intersection point from the algorithm can be used for compiling the drawn Bézier curves exactly. This algorithm is stable, accurate and rapid.
