hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I have a 3D world with random point (more or less 1000) and with some couple of point, I have a spring who rely both

(for example a and b are rely by a spring, a can't move but b can).

What I wan is after a certain time , get the stable system. example

my start system is

after the system was stable.

some poeple say I have to use ODE (Ordinary Differential Equations) library.

the only I found is http://www.gnu.org/software/gsl/manual/html_node/Ordinary-Differential-Equations.html

but is it good??

and other thing, how to use that??

the only thing I know is A(x_a,y_a,z_a) , B(x_b,y_b,z_b) and C(x_c,y_c,z_c)

and (for example ) A and B are fixed (can't move)

there is a spring with a force of 7 between A and C and there is a spring between B and C with a force of 3).

who to resolve that?

thanks a lot for all.

a+++
