Detailed Description

template<class DataTypes>
class sofa::component::forcefield::QuadBendingSprings< DataTypes >

Bending springs added between vertices of quads sharing a common edge.

The springs connect the vertices not belonging to the common edge. It compresses when the surface bends along the common edge.
