Polygon clipping differs from line clipping in several respects:
1-The input to the clipper is a polygon, which for simplicity we will view as a list of n >= 3 vertices (v0; v1; : : : ; vn-1).
2-The output from the clipper is one or more polygons
3-The clipping process may generate vertices that do not lie on any of the edges of the original polygon.
4-Complex polygons (that is, non-convex) may lead to strange artifacts.
