Are you simply looking for OpenGL smooth vs flat shading?

The OSG has a osg::ShadeModel state attribute that wraps up
glShadeModel.  Often you'll find OpenGL features wrapped up with a 1:1
mapping so just replaced the gl by an osg:: and often you'll find what
you are looking for.

To enable flat shading, above the subgraph you want to affect simple add:

   node->getOrCreateStateSet()->setAttribute(new
osg::ShapeModel(osg::ShadeModel::FLAT));
