(2) (8 marks) (a) Consider viewing using a rectangle in 2D, i.e., only the parts of objects inside the rectangle are visible and consider clipping a line segment using the rectangle. It turns out that we only need to consider the line segment's endpoints in order to determine whether it is completely visible, is partially clipped, or is completely clipped. Show this is true and draw all possible situations. (b) Do the situations you provide in 2D also apply to viewing using a prism in 3D? You don't need to provide all the possible situations and just explain as why or why not.
