Base class for a penalty term imposed on a transformed point set
Subclasses represent in particular internal forces on deformable simplicial complexes such as elasticity, strain, curvature, non-self-intersection (i.e. triangle repulsion), and node repulsion.
The penalty is minimized by the registration using an instance of RegistrationEnergy with set data similarity and regularization terms. Higher penalties lead to stronger enforcement of the constraint.
The same force terms can be used in a "non-parametric" DeformableSurfaceModel as internal force terms to regularize the evolution of the surface model.
