ASF subversion and git services commented on LUCENE-6196: --------------------------------------------------------- Commit 1677205 from [~dsmiley] in branch 'dev/branches/lucene6196' [ https://svn.apache.org/r1677205 ] LUCENE-6196: committing Karl's latest patch https://reviews.apache.org/r/33509/ (diff #6) > Include geo3d package, along with Lucene integration to make it useful > ---------------------------------------------------------------------- > > Key: LUCENE-6196 > URL: https://issues.apache.org/jira/browse/LUCENE-6196 > Project: Lucene - Core > Issue Type: New Feature > Components: modules/spatial > Reporter: Karl Wright > Assignee: David Smiley > Attachments: LUCENE-6196-additions.patch, LUCENE-6196-fixes.patch, > LUCENE-6196_Geo3d.patch, ShapeImpl.java, geo3d-tests.zip, geo3d.zip > > > I would like to explore contributing a geo3d package to Lucene. This can be > used in conjunction with Lucene search, both for generating geohashes (via > spatial4j) for complex geographic shapes, as well as limiting results > resulting from those queries to those results within the exact shape in > highly performant ways. > The package uses 3d planar geometry to do its magic, which basically limits > computation necessary to determine membership (once a shape has been > initialized, of course) to only multiplications and additions, which makes it > feasible to construct a performant BoostSource-based filter for geographic > shapes. The math is somewhat more involved when generating geohashes, but is > still more than fast enough to do a good job. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
