[vtkusers] Problem with surface reconstruction from cloud point, vtkDelaunay3D works?

Thanks for your help.
But, to my knowledge vtkDelaunay3D uses some algrythm like convex hull to construct a surface, and its
basic function is to construct a triangular nets from unstructed points, but My problem is first to pick out the
points lies on the surface from a points cloud, which has points scattered inside it. And then to construct a both
convex and concave surface from the picked points.
Anyway, I would try vtkDelaunay3D if it do works.
Is there some more suggestions?
