Re: [osg-users] where can i find the vertex positions?

If you're just interested in the vertices and not the mesh, you can look at osg::Geode, get the list of osg::Drawables, cast to osg::Geometry, then call osg::Geometry::getVertexArray(). Or you can use osg::TriangleFunctor to iterate over the triangles that make up the mesh, this provides you

Re: [osg-users] distant nodes in orthographic projection turn black

It's not erratic, it's pretty strongly correlated to the projection matrix settings (determining the zoom level), camera distance and size of the icon. I looked at the icon model, from inspecting the .osg file (converted from .ive with osgconv) it appears that the relevant state settings are:
