-------------------------------------
bq. So I think this issue can just focus on docvalues for distance?
+1
bq. We might want to do it the same way for 3D.
I'm happy to follow your lead. I was going to model the 3D Comparator/Sort
code on LatLon's. If you want to make structural changes first, let me know
and I'll hold off until you're ready.
> Add Geo3DPoint equivalents of LatLonPointDistanceComparator and
> LatLonPointSortField

> Geo3D has a number of distance measurements and a generic way of computing
> interior distance. It would be great to take advantage of that for queries
> that return results ordered by interior distance.
