I am now learning optics in school, and would like to point out the
following optic errors in POV-Ray. I don't know how realistic pov is
supposed to get, but I hope that one day these errors will be fixed.

1) When I use media/atmospheric light effects, I don't see the light
curving when it goes through lens. It keeps going the way it did.
Morever, if I point a beam into lens and watch where the beam falls on
the other side, I see that the light kept going as if it wasn't
affected. Only if I point the camera at the lens do I see the object
behind the lens in the right way.

2) When I make a wall split to two by a small hole along its height, and
point a light on to it, and then put a board behind, the light just
projects a staight line (as we would expect) but does not show the wave
property effects of light. This effect should produce dark areas across
the board.

I love POV, like all of us, and would love to see it beat nature ;)
