HI Mo, The normal way to hide/show elements are to place the elements in separate osg::Geometry attached to separate osg::Geode, then toggle the geode on/off via a NodeMask or by using an osg::Switch as a parent.
You could go the route of add/removing primitive sets but this will be more awkward to manage and you'll have to be very careful about threading issues. Robert.
