Python: Calculate Voronoi Tesselation from Scipy’s Delaunay Triangulation in 3D

I have about 50,000 data points in 3D on which I have run scipy.spatial.Delaunay from the new scipy (I’m using 0.10) which gives me a very useful triangulation.

Based on: http://en.wikipedia.org/wiki/…

How can I get a dictionary of cells from this Voronoi Diagram data?

Using the voronoi/delaunay diagram generation library found in this program, which is based on Fortune’s original implementation of his algorithm, with a random set of points as input data, I am able …

How to Bound the Outer Area of Voronoi Polygons and Intersect with Map Data

Background

I’m trying to visualize the results of a kmeans clustering procedure on the following data using voronoi polygons on a US map.

Here is the code I’ve been running so far:

input <- ...

Territory Map Generation

Is there a trivial, or at least moderately straight-forward way to generate territory maps (e.g. Risk)?

I have looked in the past and the best I could find were vague references to Voronoi diagrams. …

plotting and coloring data on irregular grid

I have data in the form (x, y, z) where x and y are not on a regular grid. I wish to display a 2D colormap of these data, with intensity (say, grey scale) mapped to the z variable. An obvious solution …

Calculate Voronoi around polygon

I need to generate a Voronoi diagram around a concave (non-convex) inside polygon. I have looked for methods online, but I haven’t been able to figure out how to do this. Basically, I generate the …

reference algorithm for weighted voronoi diagrams?

Can someone point me to a reference implementation on how to construct a (multiplicatively and/or additively) weighted voronoi diagram, which is preferably based on Fortune’s voronoi algorithm?

My …

Breakpoint Convergence in Fortune’s Algorithm

I am implementing Fortune’s sweepline algorithm for computing Voronoi diagrams. My primary reference is “Computational Geometry: Algorithms and Applications” by de Berg et al., and while their …

What’s the bounding box for computing Voronoi Diagram in boost library

Recently I am trying to use the library boost to compute Voronoi diagram.
The algorithm in this library is based on sweep-line. But it is not based on a bounding box to generate diagram. Some of …

Easiest algorithm of Voronoi diagram to implement?

What are the easy algorithms to implement Voronoi diagram?

I couldn’t find any algorithm specially in pseudo form. Please share some links of Voronoi diagram algorithm, tutorial etc.
