Simulating Chain, Rope, and then Cloth
CS 493/693 Lecture, Dr. Lawlor
By creating a 1D grid of links that pull only when stretched, we can
simulate chain. Sadly, we need 0.1ms timesteps to even approach
the stiffness of steel.
By adding a term to push back against bending, we have a reasonable simulation of rope, hose, or thick wire.
By interlinking a 2D grid of these same links, we have a simulation for
a very wimpy cloth; adding diagonals makes a fairly robust cloth

including some experimental data from a cloth-manipulating machine, see
