I have some algorithms on polygons I would like to implement. When implemented I will release my implementations as Squeak or Pharo packages under an MIT licence. What does Pharo have to offer in terms of a GUI for this? It would also be helpful if the package already had an implementation of an algorithm for triangulating polygons. An implementation of an algorithms for constructing Voronoi diagrams of a point set would also be useful. Any advice appreciated. Note: earlier I made a similar post on one of the Squeak mailing lists. Are there anyone who might be interested in my algorithms? I won't go into details here but I am likely to implement my own triangulation algorithm among others and it would be nice if this implementation in particular was used by someone or some package.
