the brackets <...> stand for the data

points:
-------
the 8 indices to the vertices of the tetra-model that will be used for steering.
the points span a quader like this (note the order):


    5-----------------------1       ----> forward direction
   /|                      /|
  / |                     / |
 4-----------------------0  |
 |  |                    |  |        ^
 |  7--------------------|--3        |  upward direction
 | /                     | /         |
 |/                      |/          |
 6-----------------------2


stiffness:
----------
the standard stiffness for all springs.


mass:
-----
the standard mass used for all mass points.
