This unexpected. I am on Debian testing and I have paraview 3.2.2. > >> (4) I apply a gliph filter and set the radius to 0.1 >> (5) I can now apply a calculator filter.

This is really the bad news. Does anyone on this list use paraview from Debian testing standard repositories? Actually, I should add now the problem of visualizing correctly the spheres appears even in the simple example with 50 particles only; there I noticed that the particles (by using radius 0.5) are actually slightly smaller than they should be (and povray also disagrees). I am puzzled; I thought all this would take minutes.
