ASF subversion and git services commented on LUCENE-8581: --------------------------------------------------------- Commit 70dd3ee06a49261da1c9d2c220f59ac9e73fc4c8 in lucene-solr's branch refs/heads/master from David Wayne Smiley [ https://gitbox.apache.org/repos/asf?p=lucene-solr.git;h=70dd3ee ] LUCENE-8581: Unreference LatLonPoint.BYTES from LatLonShape & Rectangle2D. > Change LatLonShape encoding to use 4 BYTES Per Dimension > -------------------------------------------------------- > > Key: LUCENE-8581 > URL: https://issues.apache.org/jira/browse/LUCENE-8581 > Project: Lucene - Core > Issue Type: New Feature > Reporter: Nicholas Knize > Assignee: Ignacio Vera > Priority: Major > Fix For: 8.0, 7.7 > > Attachments: LUCENE-8581.patch, LUCENE-8581.patch, LUCENE-8581.patch, > LUCENE-8581.patch, LUCENE-8581.patch, LUCENE-8581.patch, LUCENE-8581.patch, > LUCENE-8581.patch, LUCENE-8581_bytes.patch > > > {{LatLonShape}} tessellated triangles currently use a relatively naive > encoding with the first four dimensions as the bounding box of the triangle > and the last three dimensions as the vertices of the triangle. To encode the > {{x,y}} vertices in the last three dimensions requires {{bytesPerDim}} to be > set to 8, with 4 bytes for the x & y axis, respectively. We can reduce > {{bytesPerDim}} to 4 by encoding the index(es) of the vertices shared by the > bounding box along with the orientation of the triangle. This also opens the > door for supporting {{CONTAINS}} queries. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
