Hi Antonio,
I try to give my experiences with using the ProjectionCameraDecorator in
a tracked environment. There is a good documentation (it helped me a
lot) for that in
Source/System/Window/Window.dox
see \paragraph PageSystemWindowCameraDecoratorsStereoProjection
Projection Screen
or the corresponding DOXYGEN documentation ;-)

Hi guys. I tried my stereo application on my two wall CAVE and objects appeared "broken" on the screen (as if there were bent on the opposite direction of the angle between the two walls). This probably means that there's something wrong with the axis and reference frames I used to specify the positions of the corners of the walls. Which system should I use? OpenSG's one or the tracking system one? For now I used the one of my tracking system (that is in the centre of my cave) but how could OpenSG be aware of it?
you have to give the projection screen corners in tracking system
coordinates, i.e. in the same coordinates the user beacon (given to
ProjectionCameraDecorator) receives.
As u can see I'm a bit confused, so please give any help... It's very
important...
Thanks a lot
But I remember it required some fiddling around to get it right.
Perhaps you can use some known scene, like a sphere per projection
screen corner.
Hope it helps,
Christoph
