Graphics clipping
Hi I am currently going through the past exam problems and I am stuck on
this clipping problem. Could you give me some hint on how to solve it?
If we clip a polygon to a window, it is inadequate to merely perform
repeated half-space clipping on each polygon line segment independently.
Give an example illustrating why independent clipping of polygon line
segments may fail to correctly clip a convex polygon. A picture alone is
inadequate; you should also give a short answer describing the picture and
why it illustrates the problem, noting both the incorrectly clipped
polygon and what the correctly clipped polygon should be.
