   Well, at the time I didn't know what the $%&$& you were talking 
about... and surely I was busy enough to get interested on "yet another 
POV-Ray experiment" that sounded like too difficult. :)

   But now, I recently received a personal request to help with this 
very same subject, and the fact is that this time I got interested... 
I'm not sure why. So, I did a bit of my usual chaotic research, and 
finally figured out something that looks like a solution, using the mesh 
camera of course.

   See the result on p.b.images, which I think simulates the raw output 
of a plenoptic camera (like the Lytro), or so I think... because I can't 
say for sure: the info on plenoptic cameras is either very dense or too 
superficial, and seems there is no available software to try myself that 
"refocusing" thing on my images.

   In case anyone is interested, here are the sources:

   I would appreciate if someone with real knowledge on the matter could 
tell me if I got it right, or at least not totally wrong...

   Regards,
