osgEarth provides a geometry object called TrackNode. This is quite a powerful object that can allow you to display 1000's of tracks.
However this does not scale to the 100,000's or even a million.
The only way to achieve this is to use OpenGL instancing. This is the same mechanism as used for simulating grass, explosions and forests.
In addition most C2 systems the track symbols need to be fixed size. There is nothing out of the box that helps you achieve this.
The following shows 100,000 tracks;
If you are interested in how to do this contact me to arrange consultancy (I'm not publishing the code as I know my previous employer would have a freebie on me).
