Hello friends!
Is there any one who knows anything about “Polygon Clipping”, “Weiler Polygon Algorithm” or “Weiler-Atherton Algorithm”?
It's like.... when u draw 2 polygons, one over other the program should shade the overlapped area.
I would appreciate if any of u guys could help me out with this!
Thanks,
vishnu sriram
