[osg-users] setProjectionMatrix and FOV

Hello osg users,
I am trying to set the camera perspective projection to 'near'
orthogonal. I achieve desired projection by setting the FOV to some low
number (1.0).
When the projection matrix is changed in this way, the scene is
'zoomed-in'. This means, that MatrixManipulator::home does also zoom-in
and the scene does not fit to the view (using TrackBallManipulator).
It is clear what happens, but how can I prevent the 'zooming' in the
best way? I could apply some scaling factor to the MatrixManipulator,
but this seems to me not a clean solution...
many thanks,
Tomas
