An algorithm of polygon clipping against a circular window

LUO Wei,ZOU Zheng-rong(Department of Surveying and Geo-informatics,Central South University,Changsha 410083,China)  
An algorithm of polygon clipping against a circular window was given based on the correlative literatures.The basic principle is that single linked lists are used to store points of polygon and intersection of polygon and circular window.An algorithm of avoiding quadratic equation solution was used to calculating intersection.Comparing with the existing algorithm,the presented algorithm used less memory space and had higher speed.
