Karl Wright commented on LUCENE-7402:
-------------------------------------
Here's the situation. The ntersection computation needs to handle case where
intersection is off the globe entirely. The line of intersection in that case
will have no solutions when intersected with the globe.
That basically means that, in that case, we should compute the bounds based on
the intersection of both planes with the globe, where the planes are +/-
MINIMUM_RESOLUTION. We could in fact just change the way we compute bounds for
planes in general to make sure we consider +/- MINIMUM_RESOLUTION, but I need
to think that change through.
The basic idea of intersection calculation is to try and compute worst-case
envelope bounds by adjusting the intersecting planes each with a fixed offset.
The offset is MINIMUM_RESOLUTION. When the line of intersection is projected
beyond the globe, then the bounds need to be determined in another way. Not
clear what that way is yet.
