Summary: Improve accuracy of distance query for Geo3DPoint
Key: LUCENE-8577
URL: https://issues.apache.org/jira/browse/LUCENE-8577
Project: Lucene - Core
Issue Type: Improvement
Components: modules/spatial3d
Reporter: Ignacio Vera
The distance query for Geo3DPoint currently uses the GeoStandardCircle which is
only accurate when the PlanetModel is a sphere.
In LUCENE-7970. a new implementation called GeoExactCircle was added that
models an exact circle, even when the planet model is not a sphere. Because
Geo3DPoint is using WGS84 planet model, we should be using this implementation
instead. The downside is that this implementation will be slightly slower.
