I've done some of those. Not especially realistic, but I did try to "merge" the
images. Using the realworld-image in a POV-scen will not work I think so I just
cut'n'paste the POV-object into the photograph. To make this look good you have
to make sure the lighting in the POV-scene is more or less the same. Also, use a
background with a color typical to the photograph and use anti-aliasing. I0ve
done some manipulations where I could fit a POV-figure in a real-world
environment, even with some overlaps. A bit of retouching here and there...
But perhaps this is absolutely not what you mean.

Good luck,

Remco
