Subject [jira] [Commented] (LUCENE-7150) geo3d public APIs should match the 2D apis?
Date Wed, 30 Mar 2016 20:33:25 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-7150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15218802#comment-15218802

Karl Wright commented on LUCENE-7150:
-------------------------------------

If they are 2D linear interpolations, then it is not unreasonable for there to be a hit count
difference between true 3D polygons and linearly interpolated polygons.

> I'm struggling to benchmark the equivalent to {{LatLonPoint.newDistanceQuery}} in the
geo3d world.
> Ideally, I think we'd have a {{Geo3DPoint.newDistanceQuery}}?  And it would take degrees,
not radians, and radiusMeters, not an angle?
> And if I index and search using {{PlanetModel.SPHERE}} I think it should ideally give
the same results as {{LatLonPoint.newDistanceQuery}}, which uses haversin.
