GriSPy is a regular grid search algorithm for quick nearest-neighbor lookup.

This class indexes a set of k-dimensional points in a regular grid providing a fast aproach for nearest neighbors queries. Optional periodic boundary conditions can be provided for each axis individually.

GriSPy has the following queries implemented:

  • bubble_neighbors: find neighbors within a given radius. A different radius for each centre can be provided.
  • shell_neighbors: find neighbors within given lower and upper radius. Different lower and upper radius can be provided for each centre.
  • nearest_neighbors: find the nth nearest neighbors for each centre.

And the following method is available:

  • set_periodicity: define the periodicity conditions.

Requirements

You need Python 3.6 or later to run GriSPy. You can have multiple Python versions (2.x and 3.x) installed on the same system without problems.

Standard Installation

GriSPy is available at PyPI. You can install it via the pip command

    $ pip install grispy

Development Install

Clone this repo and then inside the local directory execute

    $ pip install -e .
