KnotGL is a javascript lib that uses the WebGL api to render knots:

KnotGL is a WebGL demo created by Philip Rideout which allows the user to “explore prime knots through 9 crossings, and some multi-component links through 8 crossings.” According to Dale Rolfsen in his 1976 Knots and Links, “A useful way to visualise and manipulate knots is to project the knot onto a plane—think of the knot casting a shadow on the wall. A small change in the direction of projection will ensure that it is one-to-one except at the double points, called crossings, where the “shadow” of the knot crosses itself once transversely.”

The KnotGL demo provides just that...

This is so cool. Must find a place where we can use it!!
