PolynomialRestShapeSpringsForceField

Context: Sofa.Component.SolidMechanics.Spring

Simple elastic springs applied to given degrees of freedom between their current and rest shape position

Data:

• name : object name

• printLog : if true, emits extra messages at runtime.

• 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).

• listening : if true, handle the events, otherwise ignore the events

• isCompliance : Consider the component as a compliance, else as a stiffness

• rayleighStiffness : Rayleigh damping - stiffness matrix coefficient

• points : points controlled by the rest shape springs

• external_points : points from the external Mechancial State that define the rest shape springs

• polynomialStiffness : coefficients for all spring polynomials

• polynomialDegree : vector of values that show polynomials degrees

• recompute_indices : Recompute indices (should be false for BBOX)

• drawSpring : draw Spring

• springColor : spring color

• showIndicesScale : Scale for indices display. (default=0.02)

• initialLength : initial virtual length of the spring

• smoothShift : denominator correction adding shift value

• smoothScale : denominator correction adding scale

• slaves : Sub-objects used internally by this object

• master : nullptr for regular objects, or master object for which this object is one sub-objects

• mechanicalStates : List of mechanical states to which this component is associated

• mstate : MechanicalState used by this component

• external_rest_shape : rest_shape can be defined by the position of an external Mechanical State
