Find Voronoi cell and neighbors about d3-delaunay

[mbostock]

delaunay.find

delaunay.neighbors

I’m asking about the Voronoi cell and it’s neighbors, not the Delaunay triangle at a point. Is there a simple way to go from Delaunay triangle and neighbors to Voronoi?

[mbostock]

The Voronoi is the dual of the Delaunay, so the tasks are equivalent.

So, the closest point to a given location [x, y] returned by delaunay.find is the Voronoi cell that contains that point.

And given a point i, delaunay.neighbors returns the connected points on the Delaunay triangulation, which are also the adjacent Voronoi cells.

Got it, I wasn’t sure if the Voronoi indices matched the Delaunay indices. Thanks!
