Michael McCandless commented on LUCENE-6480:
--------------------------------------------
It's great that the only spatial dep for geo3d is the spatial4j testing base
class...
We could move geo3d to sandbox to explore the integration here? Geo3d is very
new (like geopoint/bkd).
I think BKD tree could also work very efficiently with geo3d.

> [LUCENE-6450 | https://issues.apache.org/jira/browse/LUCENE-6450] proposes a
> simple GeoPointField type to lucene core. This field uses 64bit encoding of 2
> dimensional points to construct sorted term representations of GeoPoints
> (aka: GeoHashing).
> This feature investigates adding support for encoding 3 dimensional
> GeoPoints, either by extending GeoPointField to a Geo3DPointField or adding
> an additional 3d constructor.
