Subject [jira] [Commented] (LUCENE-3795) Replace spatial contrib module with LSP's spatial-lucene module
Date Wed, 14 Mar 2012 03:55:45 GMT


Chris Male commented on LUCENE-3795:

bq. I just did a quick test, and Math.toRadians was more than 3 times slower.

Big +1 to this.  There are huge benefits to be found in optimizing the actual arithmetic.
 Math.* methods are very conservative.

> I propose that Lucene's spatial contrib module be replaced with the spatial-lucene module
within Lucene Spatial Playground (LSP).  LSP has been in development for approximately 1 year
by David Smiley, Ryan McKinley, and Chris Male and we feel it is ready.  LSP is here:
 and the spatial-lucene module is intuitively in svn/trunk/spatial-lucene/.
