[Paraview] particle surface based on position

[timcfagan .]

Is there a way for paraview to generate a surface based on point positions?

Viewing particle data as a surface, it just shows the points. One way I
have generated a "surface" is to use a contour by mass on nodal points. But
this is a bit iffy as changing the mass threshold will add or remove parts
of the surface.

Attached is an image for both of these. The contour looks okay, but
probably isn't the right way to go about it...
