[jira] [Comment Edited] (LUCENE-7430) Geo3d test failure
[ https://issues.apache.org/jira/browse/LUCENE-7430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15448165#comment-15448165 ]

--------------------------------------------------------------
The north rectangle that is misbehaving is a narrow, very tiny rectangle with one point at the north pole and the other two points not far different from that. The point is coming up as being not within the shape bounds but as being within the shape. This is to be expected, however, since the point is not exactly on the world but the shape is confined to the world.
was (Author: kwright@metacarta.com):
The north rectangle that is misbehaving is a narrow, very tiny rectangle with one point at the north pole and the other two points not far different from that. The point is coming up as being not within the bounds but as being within the shape. But this applies only to the quantized point; the unquantized point is fine.
So in this case it would initially appear that we have a test problem.
We generally accept that there are some effects of quantization; once a point is quantized it potentially leaves the exact surface of the world and can therefore wind up being outside of a shape's bounds. That appears to be the situation here. The only question is: what to do about it, without making the test useless?
