> The osgViewer::Viewer updateTraversal() copies the trackball matrix across to the viewers camera on each frame. Go look at the code. It doesn't use the "Rotation matrix" as there is no rotation matrix in the TrackballManipulator, just a complete 4x4 matrix.

Thanks Robert. My problem is that I have to work only on OSG 1.1 version. So the query posted was related to 1.1 verrsion.
Hence I could not find UpdateTraversal call in 1.1.
Can anyone help me figuring out the way Viewer updates the input from trackball rotation.
