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. 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.
