Summary0008962: Allow geometry to remain constant while data arrays change
DescriptionIt would be nice to allow multiple version of a data array to be stored in a polydata. The idea being that you can have only 1 file with the geometry, and then sequentially visualize many versions of a data array without having to write the entire vtp file again (as they are often huge).

I started looking for this when writing a clustering algorithm. I have a "ClassLabel" array which stores, for each point, which class/cluster the point is associated with (an integer value). I would like to track these class associations over "time", that is, in each iteration of my clustering algorithm, I would like to save the class associations at each time point so that I could watch the evolution of the clusters in paraview. If I had 1000 iterations, it would not be feasible to write 1000 entire vtp files, but somehow storing 1000 integer arrays would be ok.

This sounds like more of a limitation with the file format than with ParaView's behavior. Why not use a file format that allows you to specify changing fields over a constant geometry. The Exodus file format allows you to do this. The EnSight might also support this, but I am not sure.
