WebbVoronoi¶. The voronoi module finds the Voronoi diagram of a set of points, while respecting periodic boundary conditions (which are not handled by scipy.spatial.Voronoi, documentation).This is handled by replicating the points using periodic images that lie outside the box, up to a specified buffer distance. This case is two-dimensional (with z=0 …
