[Paraview] Animate a single file

[Michael Koplow]

I have timeseries data which consists of several thousand spheres  
(saved as point data -- just center locations and radii) whose  
temperature changes with time.  I am able to import the locations and  
temperatures using both the legacy vtk file format and the newer xml  
vtu format.

Is it possible to animate the temperatures using a single file which  
has all of the timesteps stored as a matrix as opposed to the legacy  
animation method (one timestep per file)?  It becomes cumbersome for  
hundreds of timesteps to keep saving additional files.  It is also a  
pain to have to keep resaving the sphere center locations when they  
remain fixed.

Does anyone have an example of animating a single vtu file?  Is this  
even possible..?

Thanks!
Mike
