Hola,

I'm working on an idea and I'm not getting the results I expected, so before 
I flog this any further, I thought I'd post and see if it's even possible. 
For those who don't know what a cross screen filter is ..... check out this 
Wikipedia entry: 
http://en.wikipedia.org/wiki/Filter_(photography)#Cross_screen

So my question is is this even possible in POV? I've constructed my filter 
(I'm using the fine wire grating method) and it dosen't work as expected. I 
think I'm missing the "diffraction" element of my filter. Since this is a 
pretty sharp group I imagine someone might have a few pointers to get me 
going in the right direction .... or tell me that it can't be done.

Cheers Jim
