[vtkusers] How to generate a mesh from surface points (original surface not convex)

Hello!


I  have  a  set of unstructured points (not from a grid) that are all known to
lie  on a closed surface.
Is there a way to generate a mesh that resembles the original surface?
I had a look at Delaunay3D but I'm not sure if that's doing what I want  since
the surface the points originate from is not convex.
I  think  I  would need some kind of Delaunay3D where the mesh is generated by
the  triangles  that  are  the  smallest  possible.  Is  that   a   Delaunay3D
triangulation where the sphere radius is kept at a minimum? Therefore I wonder
if the offset parameter corresponds to a maximum radius?
It says in the docs the vtkContourFilter takes any input dataset. So how would
that create a surface from my unstructured points?
Is there any other filter I should concider?


Many thanks for any help or hints.
