Karl Wright commented on LUCENE-7157:
-------------------------------------

Still working on this problem.

There are two issues -- one having to do with pole selection, and the other 
having to do with polygons (spanning more than 180 degrees).  I'm introducing 
GeoConcavePolygon to help handle the latter case but I need to rework the 
GeoPolygonFactory method that breaks up non-convex polygons to generate these, 
and that is turning out to be algorithmically complex.  Probably will be 
working on it all weekend...

> Geo3DPoint implementation should pay attention to the ordering of lat/lon

> The LatLonPoint API implementation pays attention to the order of the points; 
> "clockwise" means one side of the polygon boundary, and "counterclockwise" 
> means the complement.  We need to use that in Geo3DPoint and convert into 
> whatever the underlying GeoPolygonFactory method requires.
