Karl Wright commented on LUCENE-8457:
-------------------------------------
Disregard the above; I was under the mistaken impressing that the shape being
looked at crossed the equator. It doesn't. In fact, it's confined to the
north polar region exclusively, so the lagrangian computation's results being
excluded are perfectly reasonable.
The point being found to be "in set" but not within bounds is this one:
{code}
[junit4] 1> point=[lat=1.4812439919751819,
lon=-3.141592653589793([X=-0.08923495159694257, Y=-1.0928129784526471E-17,
Z=0.9937907331608504])]
{code}
This represents a place in the antipodes of the shape, and is in-set because of
the narrowness of that shape. The points that are used to compute the bounds,
though, are exclusively the end points:
{code}
[junit4] 1> LLHC = [lat=1.2487354264870392, lon=0.0([X=0.3159198457087565,
Y=0.0, Z=0.9467800047525483])] LRHC = [lat=1.2487354264870392,
lon=3.5181789305199657E-12([X=0.3159198457087565, Y=1.1114625449056655E-12,
Z=0.9467800047525483])]
{code}
Since those obviously are not going to do it (they both have positive X), then
we must rely on the intersection bounds computation to find points for the
bounds. This computation is not finding a point with sufficient minus X value
to capture the antipodes -- I still need to determine why.
