Karl Wright commented on LUCENE-8136:
-------------------------------------
[~ivera] I made a few straightforward changes to it and committed it, along
with the RandomPlaneTest class. I had to disable the polygon part of that test
because of a different problem: the polygon constructor can't reliably find a
point inside the polygon when the polygon is that small. That will require
another ticket.
> Planes constructed with two points are wrong when points are close

> 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.
