> URL: https://issues.apache.org/jira/browse/LUCENE-8136
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/spatial3d
> Reporter: Ignacio Vera
> Assignee: Karl Wright
> Priority: Major
> Fix For: 6.7, master (8.0), 7.3

> Attachments: LUCENE-8136-RandomTest.patch,

>
> Whenever a plane is constructed with two points (and the center of the
> planet), and those points are close to each other,it might happen that the
> final plane does not contain all points used for the construction. The issue
> seems to happen when the resulting magnitude of the normal vector of the new
> plane (calculated using cross product) is lower that 1e-5.
> This is a follow up of issue LUCENE-8133.
