[Paraview] time series not working with xyz or lammps-dump reader && presenting millions of atoms by "spheres"

[Christian Richter]

Hi Jian,

for 1.) have a look at my liggghts text- and binary reader at 
http://web678.public1.linz.at/Drupal/?q=node/681 (you have to register 
to see the attached files) as a starting point for your own implemention.
for 2.) you can use the PointSprite Plugin, I've written a HowTo here: 
http://web678.public1.linz.at/Drupal/?q=system/files/howto_paraview.pdf

greez,
Christian
