[jira] [Comment Edited] (LUCENE-8071) GeoExactCircle should create
circles with right number of planes
[ https://issues.apache.org/jira/browse/LUCENE-8071?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16274624#comment-16274624 ]

Thanks for committing [~karl wright],
Fair to say that the shape only supports planets which are slightly elongated like WGS84 (~abs(flattening)<0.05).
I attach the test I am using to check the shape in case you think it is useful. I will move this shape to the spatial4j wrapper if it is ok with you.

> Hi [~kwright@metacarta.com],
> There is still a situation when the test can fail. It happens when the planet model is a SPHERE and the radius is slightly lower than PI. The circle is created with two sectors but the circle plane is too big and the shape is bogus.
> I will attach a test and a proposed solution. (I hope this is the last issue of this saga)
