Dear CGAL developers,

as you may recall, I am pursuing tetrahedral meshing that is faithful
to boundary features, which is now supported in 3.8. The examples
given suggest a an implicit function whose boundary points comprise a
polyline, which in turn is used as the features of the mesh domain,
and a polygonal surface mesh whose angular features are detected
automatically. The problem that I have is sort of in-between. I would
like to input an anatomical polygonal surface whose boundary must be
adhered to faithfully, but which also does not exhibit hard corners
the way that your fandisk example does, and it seems that the
detect_features() function does not result in the correct boundary
being maintained. I would consider populating a polyline, like the
other example, but I'm not dealing with an implicit function here. Is
it possible to instantiate the polyline approach with something other
than the an implicit function, or conversely get the input polygonal
surface to be espoused completely with the detect_features method?

Best wishes,

Michel

PS: I think that the output to vtk is working. I was able to visualize
a result with Paraview.
