1. Provide your answer to the following two questions about the Cohen-Sutherland line clipping algorithm. Diagrams can be used in your answer where necessary. [8 marks] a) Explain how the Cohen-Sutherland algorithm could be extended from 2D to 3D space. b) The following figure shows two lines and a rectangular clipping window. Describe the steps of clips that the Cohen-Sutherland algorithm would perform for each of these lines
