[Paraview] Not sure if I'm misunderstanding tetrahedralization

[Gregory Lewis-Paley]

Hey again,

Using a bunch of points from a csv, I'm trying to generate an image 
that's like a Delaunay Triangulation but also includes the interior 
links, much like what I picture a tetrahedralization would look like.

Problem is, the tetrahedralization doesn't seem to work on plain points. 
Am I misunderstanding the use and application of this tool?
