I agree. I should have given more clarifications :
I took fade power = 2 of course for the experimentations.
Furthermore, your assumption "the spreading of light from a flat area-light
is not realistic. That it should have a stronger intensity at the center" is
correct. (sorry if my explanaison was not clear)

The idea comes from
http://news.povray.org/povray.programming/thread/%3C4044ba89%40news.povray.org%3E/. I
don't know if it has already be used before.

I am looking forward to seeing the new povray rendering on winosi page.

Regards,

Jerome
