Ignacio Vera commented on LUCENE-7936:
--------------------------------------
"If these are insufficient for what you're trying to do, please let me know
why."
For what I see there, the classes in the package only handle points in Planet
model WGS84. I am interested in the SPHERE, indexing polygons as well as
points. My approach is more similar to the class in spatial-extras Geo3DShape
but creating my custom spatial context which wraps the Geo3dArea shapes.
"So perhaps you are going to need to do something different anyway?"
This is true for generic polygons but the polygons I am working with expand as
much as a few degrees. I made an experiment tonight creating random polygons
that expand less than Math.PI with many points. It was never decomposed using
concave polygons. I do think the library does what I need for my use case.

> Hi [~david.wri...@bksv.com],
> I would like to propose to extends the GeoShape interfaces to be able to
> copy/serialized the objects. The current status and propose change is as
> following:
> GeoPoint: It can be serialized by using x, y, z
> GeoCircle: It can be serialized by using getCenter() and getRadius() and
> getPlanetModel()
> GeoCompositeShape: It can be serialized by accesing shapes using size() and
> GetShape(int index)
> GeoPath: add methods to the interface getPoints() and getCutoffAngle()
> GeoPolygon: This is the most complicated one as we have different types:
> 1.- GeoCompositePolygon is just a composite
> 2.- GeoConcavePolygon and GeoConvexPolygon: Create a new interface for
> those polygons which exposes the points, holes, internaledges and
> concavity/convexity
> 3.- GeoComplexPolygons: Do nothing, they are too complex to be serialize??
> I am intersested in accesing the discreatization of the polygons into convex
> and concave ones for other reasons as well. I think this should be expose as
> they end result can be used for other use cases.
> Cheers,
> I.
