Hello. I joined your forum in order to inform you about some of my articles related to my graphic method designed to create polygonal spirals and other curves of any kind. This method has also allowed me to generate polygonal spirals with all the vertices in common with any logarithmic or Archimedean spiral. In my first article, in addition to the description of the graphic method, I also describe some algorithms that allow these polygonals to be created automatically. Later continuing the study of my method I made other articles on the same topic. This is the link where you can find all my articles so far written on the subject, starting from the last published. http://vixra.org/author/dante_servi Best regards Dante Servi
