Define clipping and covering (exterior clipping)?
Clipping is the process of cutting a graphics display to neatly fit a predefined graphics region or the view port.
This is just opposite to clipping. This removes the lines coming inside the windows and displays the remaining. Covering is mainly used to make labels on the complex pictures.
Implement Cohen Sutherland and Liang Barsky line clipping algorithms in C-language. Test your code for line segments with end points falling in various regions.
