"which is not deformed by perspective" = parallel projection, as opposed to a conic projection. The further from the closest cap on the cylinder its apparent size remaining the same as the cap. In a deformed projection…
We are trained on rotated mirrors in the vertical axis (Y), seldom we see them rotated on the horizontal axis (X). If you go to an hotel with mirrors on the ceiling or on the floor, the reflections are all flipped…
