[jira] [Created] (LUCENE-7154) Add support for polygon holes to
Geo3D
Karl Wright created LUCENE-7154:
-----------------------------------
Summary: Add support for polygon holes to Geo3D
Key: LUCENE-7154
URL: https://issues.apache.org/jira/browse/LUCENE-7154
Project: Lucene - Core
Issue Type: New Feature
Reporter: Karl Wright
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.
