About Knot-That-Easy ===================== - Author: Jorge A. Torres <j at jorgetorres.co> - URL: http://jorgeatorres.github.io/knot-that-easy - Source code: http://github.com/jorgeatorres/knot-that-easy Knot-That-Easy is a program useful for getting information about mathematical knots (http://mathworld.wolfram.com/Knot.html) by being able to actually "draw" a regular diagram of the knot inside the application. Features ======== - It doesn't force you to use some sort of complicated knot codification system: you can enter a regular diagram of the knot using the mouse by drawing lines, creating over and under crossings, etc. - It looks pretty nice compared to what is available right now on Linux and other platforms. - Knot-That-Easy is written in Python using PyGTK+ for the UI so it should work across supported GTK+ platforms (Windows, OS X, Linux). - Knot-That-Easy can determine the following data about a regular diagram of a knot: - # of crossings and arcs - alternance of the diagram - writhe - Gauss and Dowker codes - the Wirtinger presentation of the fundamental group of the knot - 3-colorability Requirements ============= - Python - PyGTK+ (including Glade support)
