Hi,
I don't think the frustum is calculated per se. Have a look at how
NodeTrackerManipulator.cpp (and others) uses setHomePosition(). I think
a certain camera FOV is assumed and then distance from the object is
adjusted so that the bounding sphere fits into the FOV.

Hi,
Thank for your advice. I took a look at:
http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/branches/OpenSceneGraph-2.6/src/osgGA/TrackballManipulator.cpp
But i can't find any place in the code where the frustum will be calculated.
Thank you!
Cheers,
Johannes
