Figure 1: Experiment and simulation: A simple (trefoil) knot tied on an elastic rope can be turned into a number of fascinating shapes
when twisted. Starting with a twist-free knot (left), we observe both continuous and discontinuous changes in the shape, for both directions
of twist. Using our model of Discrete Elastic Rods, we are able to reproduce experiments with high accuracy.
Abstract
We present a discrete treatment of adapted framed curves, paral-
lel transport, and holonomy, thus establishing the language for a
discrete geometric model of thin flexible rods with arbitrary cross
section and undeformed configuration. Our approach differs from
existing simulation techniques in the graphics and mechanics lit-
