A module for calculating and analyzing Voronoi tesselations

Project description

Tess, a 3D cell-based Voronoi library based on voro++

`Original work`_ by Chris H. Rycroft (UC Berkeley / Lawrence Berkeley Laboratory). This repository includes Python bindings, using Boost.Python.

Voro++ is a software library for carrying out three-dimensional computations
of the Voronoi tessellation. A distinguishing feature of the Voro++ library
is that it carries out cell-based calculations, computing the Voronoi cell
for each particle individually, rather than computing the Voronoi
tessellation as a global network of vertices and edges. It is particularly
well-suited for applications that rely on cell-based statistics, where
features of Voronoi cells (eg. volume, centroid, number of faces) can be
used to analyze a system of particles.

Voro++ comprises of several C++ classes that can be built as a static library
and linked to. A command-line utility is also provided that can analyze text
files of particle configurations and use most of the features of the code.
Numerous examples are provided to demonstrate the library's features and all of
these are discussed in detail on the library website.

.. _Original work:


`This repository`_ is a python wrapper
around the voro++ library. It is currently not as powerful as the full C++
library, but contains a number of functions.

.. _This repository:

To make, run ``python build_ext`` in either the main directory or the ``src`` directory.

To install, run ``python install --user`` to install to your home directory (recommended), or
``sudo python install`` to install to the main setup directory.

After installation, use `import tess` to import the module.

Examples of use are `available here`_,
with the notebook being rendered from ``examples/Examples.ipynb``.
