Object-oriented design: framework objects versus data containers

I find that in object oriented design, there are two kinds of objects:

  • A first kind is the object encoding logics. This is an object for which clever and complex design will hold together the logics of a state-full application. It can often be part of a forest of objects …

Minimum spanning tree

Gary Ruben came up with the excellent idea of visualizing the minimum spanning tree of a Delaunay tesselation in addition to Delaunay tessalation itself. After he sent me his code, I spent some times playing with it, because I found out that, with the right choice of visualization parameter, it …

Extracting the data from the Delaunay triangulation

Gary Ruben just asked me if it was possible to retrieve the triangulation information from my previous Delaunay example. Actually the reason I came up with this example is that Emanuelle Gouillart, my partner[*], needed to do Delaunay triangulation on some data. She was kind enough to extract that code …
