[Paraview] Doubt about animating 2 (or more) datasets simultaneously

[Moreland, Kenneth]

When animating these two datasets, ParaView will animate through 5 time values (it is better not to think about them as time steps since ParaView does not use time step indices with animating, it uses time values).  The time values will be 0.0, 0.25, 0.5, 0.75, and 1.0.  (ParaView will recognize that the time values of DS1 are also in DS2 and visit them only once.)  When at a time value that is not in DS1, such as 0.25, ParaView will load the "closest" time value available.  (I don't remember whether ParaView will round down to 0.0 or up to 0.5.  Try it and find out.)

ParaView will never interpolate missing frames by default because it can introduce artifacts.  However, you can impose interpolation if that is what you want by using the Temporal Interpolator filter.  Attach this filter to DS1 and you will get interpolated values for that filter.  This only works if the topology remains consistent, though.

Subject: [Paraview] Doubt about animating 2 (or more) datasets simultaneously

Just a simple (and probably silly) doubt:

When animating 2 datasets with different time scales simultaneously, is ParaView able to synchronize the frames? For example, let's suppose we load 2 datasets with the following timestep distributions:

DS1: 1 (0.0), 2 (0.5), 3 (1.0)

DS2: 1 (0.0), 2 (0.25), 3 (0.5), 4 (0.75), 5 (1.0)

where in n (t), n is the time step number and t is the corresponding time value. Both datasets finish at the same time instant (t = 1.0) but the "time resolution" was clearly different. In this (easy) case, how does ParaView create the movie? Does it interpolate the missing frames for the dataset 1?

Thanks for any clarification
