Karl Wright commented on LUCENE-7154:
-------------------------------------

Wouldn't "contains" have a different result if the sense of the polygon were 
different?

If you draw a polygon on a sphere (or an ellipsoid), there are two areas you 
might be specifying: one on one side of the shape you drew, and another on the 
other side.

> 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.
