What is the major difference between Cohen Sutherland and Cyrus beck line clipping algorithms? Briefly Discuss both algorithms with suitable example. In Cyrus Beck line clipping algorithm, How will you determine whether the point of intersection between line and clipping window is Potentially Entering (PE) or Potentially Leaving (PL). Derive the expression for t with respect to ith edge and PQ (line to be clipped) in the context of Cyber Beck line clipping algorithm. Use the Cohen Sutherland line clipping algorithm to clip the line segment PQ having coordinates P(20, 30) and Q (100, 100). The clipping window ABCD‟s coordinates are – A(0,0), B(40,0), C(40,40) and D(0,40)
