Hi there,

I’m currently trying to implement some animations on top of our current Vtk system.  
So far, I’ve been using the Interactor Timer Event and updating my data manually but now I need to interpolate my Series.

In order to do this, I’m currently using the `MultiBlockDataSet` to store each timestep data on a separate block and trying to use the `TemporalInterpolator` on them.

From what I could put together, I should set the TimeSteps on the `MultiBlockDataSet`'s `vtkInformation`, something like:

`info->Set(vtkStreamingDemandDrivenPipeline::TIME_STEPS(), timeSteps, numberOfTimeSteps);`

1. Is this the correct aproach to this?

The other option that has occurred me was trying to use the `TemporalShiftScale` with the `MultiBlockDataSet` as input, to actually set the the temporal info but had no luck with this aproach, I guess the data should already contain the `TIME_STEPS`

1. Could this work or is my assumption correct and I actually need to set this beforehand?

I would greatly appreciate any guidance on this matter and don’t hesitate to suggest any other aproaches as well.
