The Knot Drawer

Go directly to the applet

This quickly programmed applet is here just to create SnapPea files which you will be able to use, for example, with Snap or the Unix kernel of SnapPea.
Note that this is NOT a clean program, it was made as a quick exercise which will deserve other computations.

Usage

You draw your knot just as in SnapPea (except that, for now, there's no editing feature, just a delete key). The hints on top of canvas might help you. Once you're finished with the drawing you press the "Print SnapPea file" button which will print out a SnapPea text file in the Java Console and in the text box underneath.

Comments are very welcome, write to me.

As an application

You may want to download the jar so that it may be used as an application : DessineNoeud.jar. Which you will execute by the following command (on command line systems...):

java -classpath insertHereYourClasses.zip:DessineNoeud.jar polX.KnotDrawer.AppletApplicationMaker

Which you might put in a good shell-script file... (please note that you have to modify the classpath to point to the classes.zip of your Java VIrtual Machine) or pipe it all with snap:

.java -classpath insertHereYourClasses.zip:DessineNoeud.jar polX.KnotDrawer.AppletApplicationMaker | snap

Macintosh users can get an application (which needs MRJ).

All of these version will allow you to modify the size of the drawing canvas.
