I want to prevent convex hull so delaunay doesnt fit my needs.

I tried the following pipeline:

polyData -> vtkGaussianFilter OR vtkShepardMethod OR (vtk 5.0.1 doesnt 
contain vtkFastSplatter) -> vtkContourFilter OR vtkMarchingSquares OR 
vtkMarchingCubes

The problem may result from having less number of points? For instance, i 
have 8 points which are corners of a polyhedron. Kevin, thanks for your 
interest and help.
