I know that ususally only one camera is active.
But is there even though any way to realize two camera perspectives in one scene
?
With a top-secret super-special-wonder-trick...or other kind of POV-Ray voodoo ?

My problem is shown in the sample picture below.
In this picture the "box" in the background is rendered with the
camera in the "panoramic" mode. But the green sample-object should rendered
not disorted (just like in the normal "perspective" camera mode)

btw.
The green object is animated in my project.

Or is there really no other way, than to render  the "panoramic" background
and the "perspectiv" object speparate - and combine them in a normal
video compositing procedure?

Note that if you want to make the object look like it is attached to the walls,
you will probably *need* the panoramic camera, because the walls are distorted
in a nonlinear way, which could make it hard (and theoretically impossible) to
get a perspective-projected object's ends flush with the walls.

If the object should "hover", maybe it is possible to do it in one shot using
MegaPOV 1.2.1 and its "camera pattern" feature (which effectively lets you set
up some additional cameras whose picture you can project onto other objects in
your scene - think of a surveillance camera system). I don't know if that
supports an alpha channel though.

"camera pattern in MegaPov"...that's very interesting.
I will try to run "megpov" in "wine" (I'm using LINUX)
and try it.

Thanks for the tip.

Megapov has a native Linux version.

I'm using it right now.

Why would you want to use "wine" when you can have a native Linux binary? See
http://megapov.inetart.net/download.html (giving you the choice of generic
Linux x86 binary, AMD64, or source code).
