Karl Wright commented on LUCENE-8245: ------------------------------------- Reasoning this through, the spacing between the travel plane and the above or below plane should be exactly 2.0 * MINIMUM_RESOLUTION. That will guarantee that any point that falls between the two planes is detected in one or the other (or, very rarely, both). When I set it up this way, the LUCENE8245 test starts passing, but the testAboveBelowCrossingDifferentEdges example now fails. So I will next analyze why that occurs, and see if the problem in that case is more readily addressable. > 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 > Assignee: Karl Wright > Priority: Major > Fix For: 6.7, 7.4, master (8.0) > > Attachments: LUCENE-8245-case2.patch, LUCENE-8245.jpg, > LUCENE-8245.patch > > > When a travel plane crosses an edge close to an edge point , it is possible > that the above and below planes crosses different edges.

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. > > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
