I don't see anything about what I would have expected to be the obvious choice, so I'll ask. Why not perspective projection for all zoom levels? This involves rendering a sphere at the lowest zoom levels, but I can't imagine why it would cause problems at high zoom levels (and the sphere is the "correct" rendering in any case).

- jacobolus 5y agoA perspective projection (or an orthographic projection) is just one specific choice of projection, and for any particular use case it falls somewhere between suboptimal and entirely unsuitable. Its one advantage is that it demonstrates that the map is a picture of a spherical earth, but it shows only one hemisphere or less, and is heavily distorted away from the center
