Hi Nico, As Jason notes the frame loop is under your control so you can just add you own call yourself in your own frame loop. Another alternative is to subclass from the Viewer and override the updateTraversals() method, another solution would be to subclass from osg::Operation and then attach you Operation to the Viewer using Viewer::addUpdateOperation().
