Karl Wright commented on LUCENE-7204:
-------------------------------------
It appears as if there's potential confusion as to which way an edge goes.
Specifically, this one (from polygon 3):
{code}
[lat=-0.5516194571595735, lon=0.0([X=0.8518418310766115, Y=0.0,
Z=-0.5241686363384119])],
[lat=0.0, lon=-3.141592653589793([X=-1.0011188539924791,
Y=-1.226017000107956E-16, Z=0.0])]], internalEdges={0, 2}}]}
{code}
The plane this describes is a slice through the world that is horizontal in Y
and tilts from the negative X extreme point downwards to an exit at X=0, Y=0,
Z=negative on the other side. Because the points describing this edge are both
at Y=0, the edge can be viewed equally well as proceeding on one side of the
globe as on the other. All that determines which it is are the bounding
planes, which in this case are the other two planes of this polygon. Should
the wrong side be picked for whatever reason, then no intersection would be
detected. The fact that both p2 and p3 seem to have the same trial point
within them is a clue that this might be the case. My suspicion is therefore
high that polygon formation is where the bug lies.
