[jira] [Commented] (LUCENE-7154) Add support for polygon holes to Geo3D

["Nicholas Knize (JIRA)" <ji...@apache.org>]

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

If we're heading down the path of supporting OGC SFA and ISO 19107 for polygons I can add the ES code I use to do this. It's on my list to refactor from ES anyway but haven't put it here because of the "we're a search engine API". I was planning to refactor to S4J or JTS. Since that's going to slightly change with a refactor to core it makes sense to add/grow the necessary support here?

> 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.
