Shear distortion has been a popular formal and informal measure, whether used quantitatively or visually, in assessing the quality of mappings or the shape of elements in a quad mesh. Nevertheless, well-known energies such as conformal- and isometric-based energies do not directly target lowering shear distortion but only bound it.
