Hi Bobby,
This sounds like a really, really, really cool toy!!! :-)
Your suggestion triggered my interest because you mentioned registering real images against a virtual scene. I am currently working on an application to do this. I am using code by Reg Willson (written in C) that calibrates a "Tsai camera model": http://www-2.cs.cmu.edu/afs/cs.cmu.edu/user/rgw/www/TsaiCode.html My objective is to develop a relatively user-friendly image-based-modeling application. I already have a prototype version, but it was built in a hurry and is far from user-friendly. Sophisticated calibration like this may not be necessary for your scene (you might simply be able to line up the camera "by eye"!), but I thought I would mention it.
(BTW: Does anyone know of any good, free camera calibration routines written in Java?)
I would imagine that the overlaying of real and virtual images is fairly trivial for Java3D. I'm not using Java3D for my current project but I would imagine that there is a way of using an image as a background texture (apparently it's possible using the javax.media.j3d.Background Node, according to its JavaDocs), or using offscreen rendering and a 2D compositing algorithm.

Hi All, I am working in a rack control and monitoring systema here at CERN that will have to deal with around 400 racks full of electronics. I was thinking about adding a 3D interface and I saw some kind of example that loaded the geometry from database and changed the color of the rack with the states...and so on. This trigered a discussion about the utitlity of this... Yesterday I have an idea and I don't know if it is a dream... By the moment. I thought that since we have cameras in the rack zones I could create an interface with one panel with the real camera view and another with the virtual view looking from the same point. This would be good and it is quite feasible but then I thought that would be amazing if somehow I could merge this two panel so that I could see the video image and on top the virtual room... Anybody has think, hear, dream about something similar? Please, let me know your comments. Bobby
