Nicholas Knize commented on LUCENE-6196:
----------------------------------------
Intent and design of general utility libraries certainly vary. One thing is for
sure, they all start somewhere. IMHO this is a good start to the 3D
computational geospatial problem space and incubating it within Spatial4J
(rc-0.4.2 or rc-0.5) would give it broader exposure / potential for greater
contribution from the geospatial community.
That being said, you're the original author. I suppose its up to the community
to decide where the contribution best fits? Taking into consideration, of
course, the inability for you to continue contributing to one of the candidate
packages.

> 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.
