I am not suggesting using an orthographic projection. What I was suggesting was using a 3d earth model, which will be rendered on the screen using a perspective projection.
Does not the earth viewed from space indicate true shapes, distances, and areas?

- jacobolus 7y ago> Does not the earth viewed from space indicate true shapes, distances, and areas? Of course not. A perspective projection distorts "true" shapes, sizes, and distances more than any other common choice of map projection, and in addition leaves more than half of the globe out of sight.
