Nicholas Knize commented on LUCENE-7154:
----------------------------------------

I should add: the code validates the proper ordering (right-hand rule for 
shell, left-hand for holes) and splits dateline-crossing polys into two shapes 
so dateline crossing polys can be rewritten as a {{Boolean.OR}} of two polys.

For XYZ coordinates I'm not so sure this will be necessary for Geo3d? But you 
tell me, Karl.

> Real-world polygons (e.g. from ESRI) have holes in them.  We need polygon 
> support in geo3D that works in the same way.
> The proposal would be to change the GeoConvexPolygon constructor to include a 
> number of GeoPolygon inputs, each of which would specify a hole.  Then, the 
> GeoPolygonFactory.makeGeoPolygon() method would also need to accept a similar 
> list of GeoPolygon hole descriptions.
> This change is likely to be fairly complex because of the already tricky 
> algorithm used to create convex polygons from non-convex ones, implemented in 
> GeoPolygonFactory.
