Transfer of vertex normals smoothness between objects

Transfer of vertex normals smoothness from a donor mesh/polysurface/subd to the other mesh

Is that possible in Rhino?

Any ideas on how to do this in Rhino (transfer vertex normals)?

Blender plugin also has something like that: MESHmachine 0.6 - Normal Transfer - YouTube

It would be great for me also transfer smoothness from normal maps (texture image) to mesh
vertex normals.

I want to use that after processing the decimation of some car part scans to have mesh heavily decimated but smoothness would come from high-quality scans or from normal map texture (which could be generated as the difference between low and high polygon meshes).

In Rhino I want only to transfer normals from one mesh to another or from a normal map to a low polygon mesh. Rest I will do in other apps.

There is also a way to use freeware MeshLab software to transfer Vertex Normals from one mesh to the other: MeshLab Features: Vertex Attribute Transfer - YouTube

Do you know how to do it in Rhino?

As far as I know, Rhino doesn’t have this. @nathanletwory do you have an idea if this is possible?

You probably will have to do some programming:

I don’t know if Rhino will never overwrite any custom-set normals as the result of any operation on that mesh.
