I believe MegaPOV http://nathan.kopp.com/patched.htm has this capability through postrender{depth} or something like that

Hi All,
I know povray can produce image output.
How about outputting the zbuffer too?
I can't find any information on this, but it
would be super cool if I could get both
the image and the zbuffer output files.
Please e-mail:
