   /// \brief Marks feature edges according to two signed dihedral angles.
   /// Actually it marks as fauxedges all the non feature edges,
-  /// e.g. the edge such that the signed dihedral angle between the normal of two faces sharing it, is between the two given thresholds.
-  /// In this way all the near planar edges are marked as Faux Edges (e.g. edges to be ignored)

+  /// In this way all the edges that are almost planar are marked as Faux Edges (e.g. edges to be ignored)
   /// Note that it uses the signed dihedral angle convention (negative for concave edges and positive for convex ones);

   /// Optionally it can also mark as feature edges also the boundary edges.
