David Smiley updated LUCENE-6196:
---------------------------------
    Attachment: LUCENE-6196_Geo3d.patch

Attached is a patch file that includes this code in the spatial module under this package: org.apache.lucene.spatial.spatial4j.geo3d.
I added Geo3dShape to org.apache.lucene.spatial.spatial4j.  I also added a Geo3dRptTest class which extends RandomSpatialOpStrategyTestClass configured to use the new CompositeSpatialStrategy, and with random indexed rectangles.  Right now to keep things simple, the query shapes are always triangles created via Geo3d.  I quickly encountered a failure and I minimized it to a simple test; see testTriangleDisjointRect().

I added some toString()'s to a few classes to aid debugging but not all of them.  To those same classes I added hashCode -- but again, almost all of these classes should have these things.

I put the code up in ReviewBoard:
https://reviews.apache.org/r/33114/
I've only used that tool a little so I'm not sure if it's possible for you to upload more diff's, Karl, or wether only the creator (me) can.  If that's a problem; you could simply re-create.  I couldn't add you as a Reviewer because you don't seem to be in the system.

> 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.
