(List) Lists all spring objects by name, and displays each object's Tension and
Dampening settings separated by a slash (/). The spring-controlled object's
influence on itself appears as Self Influence, and cannot be deleted. However,
you can effectively remove the object's influence on itself by setting Tension
and Dampening to 0, resulting in no motion.
To set Tension and Dampening for one or more objects in the list, highlight
them in the list and then adjust the settings.
Tension The "stiffness" of the virtual spring between the controlled object
and the highlighted spring object(s).
Dampening Acts as a multiplier of an internal factor that determines how
quickly the object comes to rest.
With the Self Influence spring, changing Dampening has the same effect as
changing Drag. With other springs, Dampening affects only the movement
caused by that spring.
Internally, the dampening value is proportional to the tension, so as you
increase the tension and make the solution more stiff, the dampening is
increased to maintain system stability.
Relative/Absolute With Relative chosen, changing the Tension and
Dampening settings causes the new settings to be added to the existing values.
With Absolute chosen, the new settings replace the existing values.
