CLIPPING ALGORITHMS

• Clipping eliminates the parts of a scene that aren’t going to be visible in the

final display.

• Clipping can be applied to various types of graphics objects.
– Points – this is basically trivial; check to see that the point coordinates are
between the clipping boundaries.
– Lines
– Fill Areas
– Curves
– Text

• The first three are standard in graphics packages.

• Most of the algorithms apply to rectangular clipping regions
