Voro++

Three-dimensional computations of the Voronoi tessellation

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.
