Model library¶
All the names of the models follow the rule: ‘[geometry][dimension][p]_[parameterization]_[…]_[model form]’, with the simplest case as ‘[geometry][dimension]’ (e.g., ring3D
). For example, dualEllipse3D_avgR_discrete
means a dualellipse geometry in 3D, parametrized by the average radius, in a discrete form.
