Here is some code to manipulate Voronoi cells in 2D. https://github.com/jlapeyre/VoronoiCells.jl
I am developing these recent packages more or less just enough to get some research done. When things cool down (i.e. baby is grown and I get an endowed chair of free creativity) I plan to make them proper packages. I'm putting them out in case someone happens to have the same need I did, (or wants to contribute or comment). If you do use something and have a question, or want something specific documented, let me know. Of course, this should eventually be integrated into the Julia geometry packages. This code uses VoronoiDelaunay.jl to generate a tesselation. Then the objects representing cells are built from the triangles. There are a lot of choices about what to store and what to compute. The current choice is driven by my current need. The cell containing a random (as in access) point can be retrieved quickly using a standard bucket scheme. The cell stores the generator and the vertices. A simpler (undocumented) structure is provided if you don't need to lookup by random point. A few features such as area of cells are provided. John
