[vtkusers] How to create a closed surface enclosing a set of 3D points

I'm working on creating a simple visual model of small molecules. A
first simple representation (simpler than a ball and stick
representation) that I would like to create is to have a single surface
enclosing all the atoms.
This surface would be created such that 1) all atoms are found inside
the surface and 2) the surface should resemble the "shape" of the molecule.
Any pointers on how one can create such a surface, from a set of 3D
coordinates (the atoms)?
A first approximation could be to create a sphere, with a diameter large
enough to enclose all atoms. However, if one have a molecule that is
more like a tube, a tube would look better.
Perhaps there are some vtk algorithms one could use to get a custom
shape, tailor made for any molecule??
