WebbI guess you could achieve that by clipping your result by the convex hull of your points. To do that I would probably use the shapely module. Given the SO post you linked I assume you are using the voronoi_finite_polygons_2d function written in the post. So i think this could do the job: WebbThis mistake is brought on by the creation of some Multipolygons that are not interable in Shapely version 2.0.1. I changed the line to fix the issue. The new command is: return MultiPolygon(Polygon(p.exterior) for p in list(plg.geoms) My issue was resolved, and I hope this can assist others.

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.
