Summary: GeoArea failure with degenerated latitude
Key: LUCENE-10508
URL: https://issues.apache.org/jira/browse/LUCENE-10508
Project: Lucene - Core
Issue Type: Improvement
Components: modules/spatial3d
Reporter: Ignacio Vera
I hit a failure when trying to build a GeoArea using the GeoAreaFactory. The
issue seems to happen when you have an almost degenerated minLatitude and
maxLatitude and you are close to the poles. Then you might hit the following
exception"
{code}
java.lang.IllegalArgumentException: Cannot determine sidedness because check
point is on plane.

{code}
The situation is easy to reproduce with the following test:
{code:java}
public void testBBoxRandomDegenerate() {
double minX = Geo3DUtil.fromDegrees(GeoTestUtil.nextLongitude());;
double maxX = Math.nextUp(minX + Vector.MINIMUM_ANGULAR_RESOLUTION);
double minY = Geo3DUtil.fromDegrees(GeoTestUtil.nextLatitude());
double maxY = Math.nextUp(minY + Vector.MINIMUM_ANGULAR_RESOLUTION);
assertNotNull(GeoAreaFactory.makeGeoArea(PlanetModel.SPHERE, maxY, minY,
minX, maxX));
}
{code}
