Consider a line segment L in world coordinates with end points P1 = (3,2, -3) and P2 = ( -2, -1, -2) , and the orthographic volume C defined by -1<= x <= 1, -1<= y <=1, -1<= z <= -10 , viewed in the negative z direction. The projection plane is at z = -1 . Assuming an orthogonal projection: (a) Clip the line L in 3D with respect to the viewing volume C and project it onto the projection plane. What are the coordinates of the clipped endpoints of L on the projection plane? (b) Project the line L onto the projection plane and clip it against the viewing window. What are the coordinates of the clipped endpoints of L on the projection plane?
