Subject [jira] [Commented] (LUCENE-7204) Geo3d test failure

[ https://issues.apache.org/jira/browse/LUCENE-7204?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15237061#comment-15237061

Karl Wright commented on LUCENE-7204:
-------------------------------------

More analysis:

The only thing in the XYZSolid that intersects the world at all is the circle described by
Y=-0.5200593200323914.  Our algorithm will look for an intersection between any external edge
of the polygon and this circle.  If it doesn't find such an intersection, then it concludes
that the shape contains the XYZSolid.  But none of the polygon edges above are outside of
the range Y=0 through Y=-0.2968103450748192, so obviously there's no intersection.

The solid's edge points listed below are correct as well, given the current logic, but what's
weird is that path.isWithin() is true for both of these, since we already concluded that the
shape didn't go anywhere near Y=-0.52:

{code}
[junit4]   2>  Edge point [X=0.0, Y=-1.0011188539924791, Z=0.0] path.isWithin()? true
[junit4]   2>  Edge point [X=0.0, Y=-0.5200593200323914, Z=-0.8525716793307343] path.isWithin()?
true
[junit4]   2>  path edge point [lat=0.2669499069140678, lon=-0.31249902828113546([X=0.9186752334433793,
Y=-0.2968103450748192, Z=0.2640238502385029])] isWithin()? false minx=1.9197940874358586 maxx=-0.08244362054909982
miny=0.70430850891766 maxy=0.22324897495757223 minz=1.2617861422967118 maxz=-0.7332234954588774
[junit4]   2>  all area points inside shape
{code}

If both Y=-1.0011188539924791 and the point [X=0.0, Y=-0.5200593200323914, Z=-0.8525716793307343]
is within the shape, and there are no edge intersections, then the logic is correct to conclude
it's a "contains" situation.  So the question is whether the logic is justified in concluding
both of these points are within the shape.  The latter point in particular would seem suspicious.
Confirming now.
