------------------------------------
Summary: GeoComplexPolygon fails when intersection of travel plane
with edge is near polygon point
Key: LUCENE-8245
URL: https://issues.apache.org/jira/browse/LUCENE-8245
Project: Lucene - Core
Issue Type: Bug
Components: modules/spatial3d
Reporter: Ignacio Vera
When a travel plane crosses an edge close to an edge point , it is possible
that the above and below planes crosses different edges. In the current
implementation one of the crosses is missed because we only check edges that
are crossed by the main plain and the {{within}} result is wrong.
One possible fix is to check always the intersection of planes and edges
regardless if they are crossed by main plane. That fixed the above issue but
shows other issues like travel planes crossing two edges when it should be only
one due to the fuzziness at edge intersections.
Not sure of a fix so I add the test showing the issue.
