Shapely voronoi

Webb6 aug. 2024 · First start with some random points to build the Voronoi object. import numpy as np from scipy.spatial import Voronoi, voronoi_plot_2d import shapely.geometry import shapely.ops points = np.random.random ( ( 10, 2 )) vor = Voronoi (points) voronoi_plot_2d (vor) You can use this to build a collection of Shapely LineString objects. 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:
