图形系统中实用椭圆求交快速算法的研究和实现

RESEARCH AND REALIZATION OF A RAPID AND PRACTICABLE INTERSECTION ALGORITHM FOR ELLIPSES

分析了一般椭圆求交算法的缺点，提出了一种便于在计算机上实现的实用的椭圆求交算法，利用该算法简化了求解的复杂过程并防止了丢失有效交点的现象。

In this paper, the defects of the common intersection algorithms for ellipses have been discussed,and a new algorithm that can be easily realized in the CAD system has been proposed.By using this algorithm the complex calculation process can be simplified and all valid intersection points can't be lost.
