boxtree: Quad/Octrees, FMM Traversals, Geometric Queries

https://badge.fury.io/py/boxtree.png

boxtree is a package that, given some point locations in two or three dimensions, sorts them into an adaptive quad/octree of boxes, efficiently, in parallel, using PyOpenCL.

It can also generate traversal lists needed for adaptive fast multipole methods and related algorithms and tree-based look-up tables for geometric proximity.

boxtree is under the MIT license.
