This scene file attempts to recreate the algorithm of Huho Elias work at
http://www.esite-host.com/~rocketmg/models/m_string.htm
The include file has sample code to show how to use it.
Please e-mail me with any questions or comments.

I wrote something similar to this a while ago (based on the same webiste) but never
posted it. My incarnation used one 2D array
to contain pos, vel, and locking points though. This negates the need for checking the
individual arrays comply with one another.
Anyway you do it, strings are fun.

I thought of playing with a 2d array, but I've got this tied in with my
multispline.inc whenever I use it. How did you lock the points? I can
only see the third array solution.

My array went something like this...
#declare StringArray = array[n][9]
where n was the number of points in the string. Then...
#declare StringArray[i][0] = px;
#declare StringArray[i][1] = py;
#declare StringArray[i][2] = pz;
#declare StringArray[i][3] = vx;
#declare StringArray[i][4] = vy;
#declare StringArray[i][5] = vz;
#declare StringArray[i][6] = cx;
#declare StringArray[i][7] = cy;
#declare StringArray[i][8] = cz;
where px, py and pz is the position of the ith point,
vx, vy and vz is the velocity of the ith point,
and cx, cy and cz is the constraint constant of the ith point (usually only 1 for free
moving points, and 0 for fixed or locked points).
Three arrays in one :-)
