CONVEX POLYGON CLIPPING AGAINST A CIRCLE
Yanqiu Du · Computer Applications and Software · 1995
Existing polygon clipping algorithms are all offered for a rectangular window or a convex polygonal window. But polygon clipping and tilling against a circle is often required in practical use. In this paper, a convex polygon clipping algorithm based on a circle is presented. A theorem about a convex polygon P within 1 a circular window V is also given.
