In 3D Graphics, which of the following statements about perspective and parallel projection is/are true? P : In a perspective projection, the farthest an object is from the centre of projection, the smaller it appears. Q : Parallel projection is equivalent to a perspective projection where the viewer is standing infinitely far away. R : Perspective projections do not preserve straight lines.

Show answer & explanation
Correct answer: A. P and Q only
Explanation
Perspective shrinks distant objects (P true), and parallel projection is the limit with the centre of projection at infinity (Q true). Perspective projection does preserve straight lines, so R is false.
