The camera manipulators only modify the viewer's Camera's view matrix, and then it's only be the viewer pulling the values and setting them, which you can override by subclassing from Viewer if you so wish. They don't effect the scene graph. The osgManipulator's can modify the scene graph but there is a callback mechanism there which you could use to watch for changes. Other parts of the OSG like osgParticle, osgAnimation and transform callbacks don't provide a mechanism to track changes, but they are self contained and you may not need to track the changes. It really depends upon what you need to track changes for. Robert.
