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 Aspect ratio? The ratio of vertical points to the horizontal points essential to produce length of lines in both directions of the screen is known as the Aspect ratio.
Steps uses in the Cohen Sutherland Line Clipping Algorithm are: Figure: Steps for Cohen Sutherland Line Clipping STEP 1: Input: x L , x R , y T , y B
Derive the common transformation for parallel projection into a specified view plane, here the direction of projection d=aI+bJ+cK is along the normal N=n1I+n2J+n3K along with the r
