You tell me... Well I guess you just did. The 3rd dimension is time, I
presume. That doesn't change anything except how you subscript your data.
Say you have 100 samples from 100 data points. Your array will be in a form
similar to [point,sample,values] or [100,100,3] where the last dimension is
your x,y,z or u,v,w depending on if we're talking about your location array
or magnitude array. Is that correct?
In my example, I assumed 1 sample from 100 points [100,1,3] which I
simplified to [100,3]. You can change the subscripts in the example to work
with your data set. [n,*] would become something like [n,0,*] for your
first sample, [n,1,*] for your second and so on.

I don't understand what you are asking. But if you are asking if you should
add this code to the vector object. No. Stick with my example.
