[jira] [Commented] (LUCENE-8245) GeoComplexPolygon fails when intersection of travel plane with edge is near polygon point

Karl Wright commented on LUCENE-8245:
-------------------------------------

Basic on the graphic, there should be two adjoining edges intersect the travel
plane.  But the total inner crossings, added together, should be equal - same
number of inner crossings as outer crossings.  We're seeing only ONE come up as
intersecting the travel plane, though.  That's hard to do given that the other
crosses it.

> 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.
