Subject [jira] [Commented] (LUCENE-6759) Integrate lat/long BKD and spatial 3d, part 2
Date Thu, 27 Aug 2015 15:31:46 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-6759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14716861#comment-14716861

Michael McCandless commented on LUCENE-6759:
--------------------------------------------

bq.  x,y,z are always >= 0.0 right

Wait, they are not :)

The planet models have the earth's center at the origin, so they span +/- 1.0 for the simple
sphere (and a bit bigger for the squashed elipsoid)?

So I think we are in fact using the full 32 bit space now, and the int values are sometimes
negative...
