Webb`geo_shape` is a MultiPolygon, each of its sub-geometries will be either treated separately during Voronoi region generation when `per_geom` is True or otherwise the whole MultiPolygon is treated as one object. In the former case, Voronoi regions may not span from one sub-geometry to another (e.g. from one island to another Webb12 juli 2024 · I want to draw Voronoi diagram in a square boundary. I tried to use voronoi_finite_polygons_2d () function. However, its result is not what I expected.
