thanks a lot for the information. pv-meshless looks very interesting and 
I will look through it. In fact my problem is that I want to represent 
the wavefunction on a regular (but not cubic grid) were I don't have the 
connectivity but can find it through the table of nearest neighbour. But 
for now each time I try something with vtk it doesn't work so I'm a 
little bit confused ;) I'll try also another root with structured grid 
and blanking (which doesn't seem to work ).

Anyway I really find the SPH method interesting and I hope I can use it.

Take care
