Hello everybody,
I would like to have more information about Resample With Dataset filter.
I read the topic : [plot difference between two slices](https://discourse.paraview.org/t/plot-difference-between-two-slices/11299)
But i could not imagine to use the Rename Array and the transform filters.
So the question is : why does exactly the Resample filter? And why do we have to use the rename … and transform filters ?
This is to prevent further errors i could do in the future.
For example, i use the Resample filter directly to compare to systems (same bouds, but differents meshes) in 2D. And that works.
But at that time, i would like to compare two slides coming from the same 3D system, but 2slides with a rotation in between. And using the Resample… does not work.
Many thanks for explanations
BR

Hello,
unfortunately this is not possible.
It’s the overall philosophy / way of doing things that interests me.
I know that the best way would have been to apply it to my data.

It resample data from one dataset to another.
> And why do we have to use the rename
To avoid the data with the same name get replace during resampling
> transform filters ?
To displace the data for easier visual inspection.
