Question

In3D computer graphics, one needsto represent 3-dimensionalobjectsonaplane screen, by drawing a given point P at the place where the line from P to the eye meets the screen. Suppose that the screen is the yz-plane, and the eye is at E :(2, 0, 0).
a)At whatpoint Q :(y,z)in theyz-plane should one represent thepoint P :(x0,y0,z0)? (Express y and z in terms of the coordinates of P. Assume that x0 < 2. Why is this assumption legitimate?)
b) What does the image on the screen of a line segment in space look like? (Justifyyour answer.)
c) A line segment connects P0 :(−1,−3, 1) to P1 :(−2, 4, 6). Wh
