Karl Wright updated LUCENE-6487:
--------------------------------
Attachment: LUCENE-6487.patch
Updating the patch with "completed" functionality, although incompletely tested
and with a known problem. Specifically, paths are specified with a half-width
for the straight segments, and that's been specified as an angle to date.
That's fine, but with an ellipsoid, a pair of planes describing the corridor in
that way might well fail to line up with the circles at the waypoints. We
really need to determine the bounding planes in a different manner to be
consistent. Something I will need to work out.

> WGS84 compatibility has been requested for geo3d. This involves working with
> an ellipsoid rather than a unit sphere. The general formula for an ellipsoid
> is:
> x^2/a^2 + y^2/b^2 + z^2/c^2 = 1
