Can anyone tell me how to apply some angular constraints or torsional forces
with povray/megapov? I started to use some mechsim.inc tools for my
molecule-animations. In the first few tries, the molecules collapsed because
the connections only act as springs (for the distance). What I need to add is
either some kind of torsional stiffness, or better, some angular stiffness
between two connections. How would I do that?
