Question

Compare Cohen Sutherland and Cyrus beck line clipping algorithms, with suitable example of each. In Cyrus Beck line clipping algorithm, How will you determine whether the point of intersection between line segment and clipping window is Potentially Entering (PE) or Potentially Leaving (PL). Derive the expression for the parameter (t) with respect to ith edge and the line segment PQ (line to be clipped) in the context of Cyber Beck line clipping algorithm.

Cohen-Sutherland and Cyrus-Beck are two well-known algorithms used in computer graphics for line clipping. Let's delve into comparing these algorithms and then discuss how to determine whether a point of intersection is Potentially Entering (PE) or Potentially Leaving (PL) in the context of the Cyrus-Beck algorithm.

### Cohen-Sutherland Algorithm:
The Cohen-Sutherland algorithm is a line-clipping algorithm that uses a divide-and-conquer strategy. It divides the 2D space into nine regions by using a 3x3 grid based on the clipping window, and then determines which portions of the line lie inside the clipping window and which portions lie outside. The algorithm is efficient for clipping lines against rectangular windows.
