Alain,
Interesting idea. Thinking through it though, for my application, i think it
would not work. Shadows grow with the distance of the object to the screen.
Using parallel projection is not going to give me that effect. Also my screen
is not paralell to the mirror glass. (I think I did not mention that in my
scene description, sorry.) Thanks, anyway!
