Dear ParaView users,
as a simple example I want to project precipitation data from a sphere on a cylinder.
I have the sphere (precip.vtu) containing the data as unstructured mesh.
Then I created a cylinder from `Sources->Geometric Shapes->Cylinder` around the sphere as the second mesh.
I then used the `ResampleWithDataset` function (cylinder as source geometry and the sphere (precip.vtu) to map the data of the sphere on the cylinder .
It outputs the cylinder and shows the resampled data arrays, however, the values are zero.
I cannot imagine what is wrong.
Does somebody has any suggestion?

Hi,
It is more straight forward way to project coordinates onto a cylinder geometry than to interpolate data using ResampleWithDataset.
Here is the state file as example:

Hi @Kenichiro-Yoshimi,
thanks for the hint!
However, my original intention is to project data from one meshfile onto an unstructured meshfile with different geometries.
The spherer-cylinder projection was just a more simple example.
That’s why I tried `ResampleWithDataset`.
Do you have any suggestion of how to prject data from one mesh onto another if geometries differ?

ResampleWithDataset does not do what your are describing.
Projecting one data into another one is not implemented in ParaView and is frankly a very hard problem.

Ok.
For me it did sound so from the [docs](https://kitware.github.io/paraview-docs/latest/python/paraview.simple.ResampleWithDataset.html).
What is ResampleWithDataSet doing instead?

Resampling does not mean projecting.
Resampling means extracting the values from source1 into source2 geometry.
