Data:

Name Description Default value
name object name unnamed
printLog if true, emits extra messages at runtime. 0
tags list of the subsets the objet belongs to
bbox this object bounding box
componentState The state of the component among (Dirty, Valid, Undefined, Loading, Invalid). Undefined
listening if true, handle the events, otherwise ignore the events 0
isCompliance Consider the component as a compliance, else as a stiffness 0
rayleighStiffness Rayleigh damping - stiffness matrix coefficient 0
points points controlled by the rest shape springs
stiffness stiffness values between the actual position and the rest shape position
angularStiffness angularStiffness assigned when controlling the rotation of the points
pivot_points global pivot points used when translations instead of the rigid mass centers
external_points points from the external Mechancial State that define the rest shape springs
recompute_indices Recompute indices (should be false for BBOX) 1
springColor spring color. (default=[0.0,1.0,0.0,1.0]) 0 1 0 1
activeDirections Directions in which the spring is active (default=[1,1,1]) 1 1 1
