David Smiley updated LUCENE-6196:

Assignee: David Smiley
Issue Type: New Feature (was: Improvement)
Cool; I'll have to dig into this in the upcoming week. If I'm not mistaken,
you are already an ASF committer for ManifoldCF and thus you already have a
contributor license agreement on-file?
I took a quick peek at ShapeImpl.java. What would it take to implement the
bounding-box? It's not strictly necessary but it helps performance a lot.
> Include geo3d package, along with Lucene integration to make it useful

> 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.
