I do work in trackball mode. What I am trying to do is to change with keyboard the position from were the camera is looking to the central node. I introduced the next in handle function.
if (ea.getKey()==osgGA::GUIEventAdapter::KEY_Tab)
{
flushMouseEventStack();
_thrown = false;
osg::Vec3d eye(0.0,-60*bs->radius(),0.0);
osg::Vec3d center(0.0,0.0,0.0);
osg::Vec3d up(0.0,0.0,1.0);
computePosition(eye,center,up);
us.requestRedraw();
us.requestContinuousUpdate(false);
return true;
}
When Tab is pressed the colocation of the camera is ok, up vector is 0,0,1 but when I press F2 where the value of the eye is (60*bs->radius(),-60*bs->radius(),0.0) is not. I thought the problem was with the value of up vector.

Hi Maider,
The NodeTrackerManipulator assumes a local z up as the up vector which
it rotates about. There isn't any customization available to alter
this. There is a trackball mode in the NodeTrackManipulator which
doesn't care about up orientation, perhaps this would be appropriate.
