Anyone know how to clip a convex polygon against another convex polygon?
The basic algorithm goes like this:
for every edge of the clipping region
for every edge of the polygon
clip polygon against clipipng region line
I can't figure out the details of this algorithm. (i.e how to communicate the vertex data from one iteration to the next)
Don't post replies about clipping lines ( i am well aware of the mathematics behind it ).
