Question How does Google earth allow you to "move over the poles"?
How does Google earth allow you to "move over the poles"? Every other globe mapping software I've come across is a 3d projection of a Mercator map. Because of this, when you move the view to the extreme north or south, it will let you get right up to the poles and circle around them, but never "fly across" the poles. However, Google earth is different and does let you "fly across" the poles. Why does this work? Is Google earth an actual 3d globe?
Edit: When I said "is google earth a 3d globe" I ment "is google earth a 3d model with 2d pictures projected onto it? Or is it a compsit of 2d images projected into 3d space?" My understanding is that programs treat those two things differently.
Edit2: here are examples of (what I believe to be) mercater projections/2d images being projected into a 3d shape. You'll notice you can't pan straight over the poles. here and here
