Finds the indicies of the Voronoi nodes that define the facet or ridge between the Delaunay nodes connected by the given throat.
throats (array_like) – The throats whose facets are sought. The given throats should be from the ‘delaunay’ network. If no throats are specified, all ‘delaunay’ throats are assumed.
The method is not well optimized as it scans through each given throat inside a for-loop, so it could be slow for large networks.
