[Paraview] Particle Simulation and Paraview modification?

[Viksit Gaur]

Hi Samuel,

Sorry, I was unable to respond earlier - was away. I checked out ensighy 
as you suggested, and I'm not sure about a couple of things which I 
thougt you might answer for me.

Ensight is a separate application, and I assume its expensive as well :) 
  When you say that I can use either Ensight 6, 8 or Gold formats, I 
guess you mean that my data can be exported in the desired format, using 
a custom program? VTK-XML seems to be something not very well suited for 
my work, the reason for which is given below.

Secondly, you're right about me having to look at a lot of datasets - 
mostly, rather large particle data sets over time. Are there any 
tutorials out there which might help me write a reader which can work in 
Parallel? Or does the ensight reader work in parallel?

Thanks,
Viksit
