Johnson-Mehl tessellation
Instructions for use
The first slider controls the intensity of the arrivals process. Set the intensity, then press "Generate new tessellation". The second slider then changes the time so you can see how the Johnson-Mehl model looks before the coverage time.
Generated with the algorithm by Hervé Moulinec published as A simple and fast algorithm for computing discrete Voronoi, Johnson-Mehl or Laguerre diagrams of points
