In the context of 3D computer graphics, which of the following statements is/are true? P : Orthographic transformations keep parallel lines parallel. Q : Orthographic transformations are affine transformations. Select the correct answer from the options given below :
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: A. Both P and Q
Explanation
Orthographic projections are affine and so keep parallel lines parallel.
