Hello. Yes, it is quite slow. I used Delaunay triangulation to build the diagram, I’m not sure that it has the smallest complexity, but it is the simples one for me. > I've seen > the code copies collections a lot, that might be it… It is the reason, however I wanted not only draw the diagram as a lot of segments, but to build the polygons and for that I need all that collections. Maybe I will change the algorithm, that builds the diagrams. Thanks for your attention and comments)
