I also implemented a very simple filter to merge the time steps like you want. The source, complete with plugin, is attached to this message. The attachment may or may not make it to the paraview users’ list.<BR>

No such filter exists right now, but it would be straightforward to implement.<BR>

files, you could create one vtk file where the third axis represents<BR>
time. You could then use slice or extract subset filters to get the<BR>
plane that you want. You can do something similar for a file series<BR>
but you would have to write a custom filter in C++ (Python would not<BR>
do).<BR>
