TestGeo3DPoint.testGeo3DRelations() failure: invalid bounds for
shape=GeoStandardPath
[ https://issues.apache.org/jira/browse/LUCENE-7357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15351034#comment-15351034 ]
Karl Wright commented on LUCENE-7357:
-------------------------------------
This path is extremely short path that is solely in latitude, length 2.18e-12:
{code}
[lat=2.18531083006635E-12, lon=-3.141592653589793([X=-1.0011188539924791, Y=-1.226017000107956E-16, Z=2.187755873813378E-12])],
[lat=0.0, lon=-3.141592653589793([X=-1.0011188539924791, Y=-1.226017000107956E-16, Z=0.0])]]}}
{code}
The bounds that is violated is in X:
{code}
xmin=-1.0011188549924792 xmax=0.4449938894797613
{code}
The point that is outside this bound but inside the shape is:
{code}
[junit4] 1> unquantized=[lat=-2.848117399637174E-91, lon=-1.1092122135274942([X=0.44586529864043345, Y=-0.8963498732568058, Z=-2.851304027160807E-91])]
[junit4] 1> quantized=[X=0.44586529870253566, Y=-0.8963498734280969, Z=-2.3309121299774915E-10]
{code}
Not clear why the x-bound computation is off here; will have to analyze how that's being done and look for numerical instability. It's possible that the issue occurs because of the approximations that must be made for endpoint circles for paths (which are really ellipses).
