D3's geoOrthographic projection works great for a hemispherical map projection.

It doesn't path out anything not "visible". This is useful in a typical map scenario, but I want to transition smoothly between Orthographic and Equirectangular maps, which gets super funky because the number of points for each path are significantly different.

(there are two hemispherical maps here, a "fore" and a "back", which is why it looks spherical)

Is there another type that does the same but "wraps" the full sphere (I didn't see one in the docs), or a straightforward way to fix the transition issue?
