question about kangaroo's simulation of wool paths

Hi,

guys, i have an urgent problem of simulating the wool paths like frei otto's experiment.

Seems kangaroo is capable of solving it, but i have no idea how to do that.

does it involve any kind of vb.net code?

seems it is recursively check the closest pt on the closest curve.

can anyone helps me out?

cheers
