- - **Geometrical approximation**
-this field as well as the Chordal deviation tolerance parameter,enables the user to bound the maximal chordal deviation allowed. it avoids having sharp angles. , that is, the maximal distance allowed between the detected curve and the plane of the corresponding mesh face. It avoids having faces too far away from the curve they represent.
+ if not set (ridge detection disabled ), MeshGems-SurfOpt will not try to detect any new ridge edge by its own mechanism :
+ it will consider as ridge only the ridges given in the mesh. All non-ridge edges that would have been detected as ridge by the Ridge angle parameter (see below split edge) will be considered as part of the same continuous patch. This option should not be checked when all the known ridges of the mesh are given and when all other possible ridges are not geometric ridges to take into account.
