Question

Difference between line clipping and polygon clipping​

Answer 1

Step-by-step explanation:

note the difference between this strategy for a polygon and the Cohen Sutherland algorithm for clipping a line.the polygon clipper clips against 4 edges in succession, whereas the line clipper tests the outcode to see which edge is Crossed, and clips only when necessary.

Answer 2

The difference between line and polygon clipping is that the polygon clipper always clips against or along the 4 edges that too in succession.

Detailed answer

The line clipper does a small test to check whether the outside edges have crossed or not.

• The line clipper only clips when necessary but the polygon clipper may clip even when not necessary.
• Polygon clipper is an important function that the computer does all the time
• Multiple polygons can result from a single polygon.
• It is usually used for hidden line problems in graphic design.
