Hi guys:
I've being posting some questions all related to the fact that I'm doing a video
with both pov and real images (video).

Part of this video takes place on a room and my approach has been to built the
room in cg so I can mix real recorded images with my pov-created room. But for
the moment, this images are entirely video recorded or cg. But what would be
interesting is to mix them so I can introduce pov into video.

I know there are tools in 3Dstudio and Maya to do that. And I know aswell there
are not such kind of tools in pov. But do you know about jobs on this? Someone
has tried to integrate cg on photos or video with pov? Are there written
protocols or tutorials to do this with pov?

Thanks

Sounds like we need Rune here...

See his Illusion include file:
http://runevision.com/3d/include/#96

especially section 5.3 of the readme inside:

"5.3   Photo manipulation tool
******************************
If you have a photo, picture, drawing, or whatever, and want to place 
raytraced objects in it, casting the appropriate shadows, then the 
Illusion Include File might be your answer.
Imagine you have a photo of a desktop and you want to place a raytraced 
object on it. First look at the photo as if it were a raytraced picture. 
  Figure out where the desktop is located relative to the light_sources. 
  Try to model the scene. Just make a simple flat box for the desktop 
and add the light_sources. Make sure that the sum of the intensities of 
the light_sources equals to rgb 1. Make a distant plane or very big 
sphere that covers the whole background. Now add the photo to the whole 
scene as an illusion texture. The hard part is to make the photo line up 
correctly with the modeled objects. In the finish of the illusion 
texture use an ambient value that matches the ambient light in the 
photo. Make the sum of the ambient and the diffuse value equal to 1 and 
use brilliance 0.  Now you should be able to place objects on the 
desktop and watch them cast the right shadows."

Maybe this is relevant as well:

Hi again:

I have seen the work of this guy and it is incredible. And the way he did it
(the hologram trick) is exactly the way I wanted to do. The major problem is to
track the camera movement... I'll try to overcome this problem but I still dont
know how.

Another problem is to adjust the quality of your cg to the quality of your video
image. The first one uses to be much better than the second one. Anyway, lets
see what can I do with pov and a video camera.

You probably already read that the program used to be free, not anymore, 
and Rune isn't allowed to redistribute it due to license...

Well, I found this site, with a permitted redistribution:
http://www.peerlessproductions.com/tuts/pages/Icarus.html

Seems to be "educational use only", though.
