Hi folks.
Is there a way to get POV-Ray to render an image using "depth queing?" That
is, having the brightness of each pixel be (linearly) proportional to the
object's position on the Z-axis. I can't currently think of a way to do
thing...
(In case you're wondering... I wanna feed POV-Ray's output into a SIRDS
generator ;-)
Thanks.
Andrew.

Here are two :
- use a black fog
- use a gradient texture (I have used this one to fake focal blur in
post-process)

For focal blur you should use a spherical pattern translated at the
camera position and not a gradient. With small camera angles this does
not matter much but it is also easier to set up (you don't need to worry
about camera view direction).

Yeah... that was the only one that occurred to me (after a while, I might
add).

Mmm... had't thought of that... sounds like it might be quicker... although,
I suppose there's not much in it!
Thanks.
