Mathematical Concept and Method of Clipping

A New technique for clipping is developed that describes clipping in an exactand mathematical form.The basic ideas form the foundation for a family of algori-thms for line clipping and polygon clipping.This analysis is then embedded in an algorithm.It is shown in performancetests using random data that the new algorithm is much faster than the Sutherlandclipping algorithm.The execution time of new algorithm is about half of what isrequired by the old one.
