Here are some links to a table of knots, up to 9 crossings, built as three-dimensional objects.
If you can achieve stereoscopic vision with two adjacent pictures, you can see the knots "in 3D".
- applets with larger width in pixels (for those who can achieve stereoscopic vision easily and/or use high resolution screen or small monitors).
- applets with smaller width in pixels (for those who have difficultty in achieving stereoscopic vision and/or use low screen resolutions or large monitors).
(*) The routines for the creation of the 3D curves were written essentially by Vítor Sousa, according to a detailed plan previously suggested in the scope of "Estágio". (Ramo Educacional da Licenciatura em Matemática - F.C.U.P - 2000/2001.). That subject acted as a guideline for a first contact with Mathematica.
