Yep, vtkDelaunay3D will only give you a convex surface while
vtkSurfaceReconstructionFilter can cope with concavities and holes. 

Having said that, if you know that your surface is convex then
vtkDelaunay3D (followed by vtkGeometryFilter if you just want the surface
triangles) will be the better choice, it is much more reliable.

Cheers,

Tim.
