[vtkusers] broadcasting an vtkUnstructuredGrid

[Martin Baumann]

Hi,

what would be the best way to broadcast a vtkUnstructuredGrid using 
vtkMPIController and vtkMPICommunicator?
At the moment proc 0 reads the UGrid and sends it to the other 
processors within a for loop.

There is vtkMPICommunicator::Broadcast(...). But there is no one for 
vtkDataObjects.
So I could split the UGrid of proc 0 into arrays of double, floats and 
ints containing point coordinates, cell information, and so on
and I could do a broadcast with these. And thereafter merge the data to 
the UGrid on the other procs.
But this way is some circumstantial.

What would you commend?

Regards, M.B.
