It is worth noting that the Principal Curvatures and Directions can also be estimated using the
\ref PkgJetFitting3 package, which estimates the local differential quantities of a surface at a point
using a local polynomial fitting (fitting a d-jet). Unlike the Interpolated Corrected Curvatures,
the Jet Fitting method discards topological information and thus can be used on point clouds as well.
