rdfpy is a Python library for fast computation of 2D and 3D radial distribution functions.

Installation

$ pip install rdfpy

Usage

import numpy as np
from rdfpy import rdf

particles = np.random.uniform(0.0, 20.0, size=(2500, 3))  # random particles in a 20x20x20 box

g_r, radii = rdf(particles, dr=0.1)

You can find a more detailed example in the Documentation.

Note: In order for rdfpy to work correctly, your particles should spatially be in a cuboidal box, where the entire box is filled with particles.
