[vtkusers] Best Particle Based file format

[George Zagaris]

Yes, you are right. In what I described, you would need a file for
each time-step. I don't know of an already implemented reader/writer
that would allow you to store multiple time-steps in a single file. I
cc'ed the list in case someone else has more ideas on this.

Best,
George
