Outside the Field-of-View
Clipping, as we discussed the lecture before last, addresses the problem of removing those objects
outside of the field of view. Outcode clipping attempted to remove all those objects that
were entirely outside of the field of view (it came up a little short of that goal, however).
Frustum clipping, as demonstrated by the plane-at-a-time approach that we discussed, removed portions
of objects that were partially inside of and partially outside of the field of view.
