From: Shape analysis of railway ballast stones: curvature-based calculation of particle angularity
Comparison of different degrees of mesh simplification and artificially rounded meshes for different angularity indices: (a) scaled total curvature: \(\widehat{{t}_{c}}\), (b) scaled Willmore energy: \({\widehat{W}}_{e}\), (c) \({I}_{A}\) angularity index from19.
