Tonight I sat down and played a bit with VTK’s Delaunay tessalation filter. I wanted to inspect the local structure of a graph created by Delaunay tessalation of random points. To see better the structure, I selected a slab of the resulting unstructured grid. I think the image is not only instructive to explain what a Delaunay tessalation is, it also looks pretty cool. Here is the image and the Mayavi script that creates it.
