Hi Flavio,
I use the POLYDATA format to save the data and then visualize it with
glyphs (usually spheres, but if you just need points I suppose small
cubes would work as well). The header looks like:

By default, ParaView draws cells, not points. (You've found one
exception where
selected points are drawn.) If you want to see points in general, you
will need
to create "vertex" cells. One way to do that is to run your data
through the
glyph filter and select the "2D Glyph" and then "Vected" glyph types.
etc.

I run Delaunay 3D on my cloud. I exported into a vtk file.
Reimported.
Only point on cube faces are displayed, no one inside
Any hint?
Best
