This is something we use deep in the engine for visibility culling. For simple examples, check out the tests:
For a full use case, see:
I'm trying to find the geographic coordinates at a certain point when I approach the globe and add 3D models, or labels geometries when I position the camera and when I remove the focus can remove. (Not worrying about performance until then).
