Karl Wright commented on LUCENE-6480:
-------------------------------------
It also occurs to me that I don't fully understand how you intend to perform a
fast search involving geo3d for records that are within a specified geo3d
shape. Perhaps you could clarify in general terms how you would foresee doing
that? I get that you are basically using recursive descent, intersecting with
the ordering in the posting list, but then I get fuzzy. What kind of boolean
decisions need to be made? Is membership of a point within the shape
sufficient? Point me at the technique as written up elsewhere if you like...

> [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.
