The mesh is from Daniel Piker's blog.The MeshVertices are welded.First of all I separate the mesh into small pieces which is constructed by point grid.And each small piece can be convert to Nurbs.…

The algorithm is simple.

First step is to build a surface Normal field.And then use laplace equation to draw the polylines on which each normal are perpendicular to a same vector.  

The cons are obvious.Cause I use the  Normal field to draw polylines. Each mesh face is not quite…
