The KnotPlot Site

Welcome to the KnotPlot Site!

Here you will find a collection of knots and links, viewed from a (mostly) mathematical perspective. Nearly all of the images here were created with KnotPlot, an elaborate program to visualize and manipulate mathematical knots in three and four dimensions.

Knot Pictures

Check out the mathematical knots (M) page as well to see more knot pictures. Or try some of the following examples to see some knots in a different light. The pages marked with have been updated or created as of May 2006. Those marked with an M have at least one MPEG animation.

KnotPlot features

Knots can be loaded from a database of more than 3,000 knots and links or sketched by hand in three dimensions. Also, knots may be constructed via the Conway notation or using the tangle calculator. A number of special knot types (torus knots, knot chains, Lissajous knots) may be created on the fly. Finally, new knots can be created from old knots by various tranformation tools. Using all these features allows the creation of quadrillions of different knots (and many more).

Acknowledgements

A big thank you to Dale Rolfsen, Jonathan Simon, and Greg Buck for much inspiration and support, especially for getting me started on the KnotPlot project.

Initial KnotPlot development was funded in part by the Department of Computer Science at the University of British Columbia (UBC/CS), the Media and Graphics Interdisciplinary Centre (MAGIC), the Pacific Institute for the Mathematical Sciences (PIMS), and the Centre for Experimental and Constructive Mathematics (CECM). The hugest of hugs to PIMS, CECM, and UBC/CS for hosting the KnotPlot pages over all these years.
