- **Ridge detection**
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 paramaeter (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.

- **Point smoothing**
When not set (point smoothing is disabled), MeshGems-SurfOpt will not try to move the initial given vertices (along an edge, a ridge or onto the surface), hence MeshGems-SurfOpt will only swap edges, remove vertices or add vertices (refines) to change the mesh.
- **Mesh gradation**
-This paramater P controls the element size variation : MeshGems-SurfOpt will avoid having two adjacent egdes which sizes vary more than th given gradation. a size correction is applied to the size map : if two adjacent edges are respectively e1 and e2 long and e2 > Pxe1, then, the new size for the second edge will be set to P x e1.
-**This procedure is desactived if P=-1**
