Is there a way to get a depth queuing effect in POV? That is, were
objects that are behind other objects get faded into the background
color, or from a certain plane backward through the image, objects are
faded into the background.
Any advice or help is appreciate.
Mike

Perhaps try a constant fog in the background colour?

Look at the help about fog in the povray documentation.

The problem with fog is that you can either hav it everywhere or from
the ground up. I need something that is like an xy-plane which fades
to the background color along the +ve z-axis.

perhaps this sounds hardly but it's really simple - just try rotate
whole world

Change the up vector of the ground fog, or use media (probably of the absorbing
type)

Ie you want distance from the xy plane, not the camera point, right? I'm not sure
you can do that in standard POV.

Unfortunately, I think you are right. Maybe a consideration for a feature in a
future version.

I added this feature in my patch that works for normal fog
and ground fog. The new parameter is 'fog_start', which specify an
offset from the camera. Only to mention that a small bug has been
recently discovered; it affects transparent objects using 'clipped_by'
modifiers.
