Cohen Sutherland algorithm
Point clipping is very simple. All you need to check is whether a point is inside the window extremes in x- and y-directions. For line clipping several algorithms have been introduced over the years and many refinements have also been suggested by people in order to improve the performance of the algorithms. One of the first algorithms that is still being used in applications is Cohen Sutherland algorithm.
What is resolution? Ans. The maximum number of points that can be shown without an overlap on a CRT is known as resolution.
Projections - Viewing Transformation Specified 3-D object in a space, Projection can be explained as a mapping of 3-D object into 2-D viewing screen. Now, 2-D screen is termed
