Robert, is there a quick way to simply update near and far clipping planes for perspective projection, without calling an explicitly redraw (I mean, some visitor that computes for example the bounding box of the model and updates near and far clipping plane also)?

You can do what you want with the near + far clipping planes in orthographic and perspetive projections simply by switch off the automatic compute of the near and planes via camera->setComputeNearFar(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR); But this won't make othrographic magically appropriate for doing internal views.
