First, are you using 1.x or the newer 2.x or 3.x series?  The latest 
release is 3.1.0 with a 3.2.0 out soon.  I would strongly recommend 
using that.  More details are here:

Are your points random or is there a structure to the points.  For 
example do you have a "grid" associated with your data?  You will need 
to first figure out how best to map your data into a format that Mayavi 
can display.  Gael has a nice and visually appealing section he wrote on 
some details here:

I think that should get you started on how best to map your data into 
the VTK/Mayavi world.

HTH.
