> 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)

>
> 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.
