I'm trying to visualize stuff like buildings and roads on the surface of the Earth. But for reference, I'd also like to display the surface of the Earth (just as a set of points). Including geometry for the Earth's surface makes the other stuff disappear (and reappear at certain angles). To me it looks like an issue with the near/far planes of the frustum. I wanted to avoid specifying the near/far planes manually since the behaviour without the Earth surface geometry is perfect as is. I don't care about the overhead of drawing the surface geometry since its so simple, and I don't want the scene graph to account for the surface geometry (outside of rendering it); the other objects in the scene should determine the camera frustum.
