I haven't read the whole thread, but I've got an idea to make your
simulation more realistic. At first sight it seems obvious that every
"mass" in your rope is connected only to its two immediate "neighbours" (n
is connected to n+1 and n-1). If you connect them to their "second
neighbours" as well (n-2 and n+2) you'll probably get a more realistic
bending. But as I'm writing this I'm becoming unsure it will work well with
a single line of springs. If you replace this single line with much more
masses and springs, and give your rope a dimension along the other two axes
as well, you can get more interesting effects too (like twisting of the
rope). Sorry for my unprofessional use of words, I hope it's still
understandable. :)

Yeah, I think I get what you're saying... I'll see how that works - if I can
figure out the maths! lol

Thanks.
Andrew.
