Detailed Description

template<class DataTypes>
class sofa::component::solidmechanics::spring::RestShapeSpringsForceField< DataTypes >

This class describes a simple elastic springs ForceField between DOFs positions and rest positions.

Springs are applied to given degrees of freedom between their current positions and their rest shape positions. An external MechanicalState reference can also be passed to the ForceField as rest shape position.
