Hi @lassoan, I am currently trying to convert my unstructured grid to a volume. So I can import it into Slicer and export it as DICOM images. The process I’m following is:

1. Create my input file:

- Convert UnstructuredGrid to Polydata with GeometryFilter
- Convert PolyData to empty ImageData with PolyDataToImageStencil and ImageStencil
- write input file

1. Use the vtkProbeFilter

- read input file
- read original unstructured grid as source file
- write to file.

You have previously provided an example of how to do this, [https://github.com/lassoan/SlicerNotebooks/blob/master/UnstructuredGridToVolume.ipynb](https://github.com/lassoan/SlicerNotebooks/blob/master/UnstructuredGridToVolume.ipynb), however this is now unavailable.

I wanted to know if my method was correct, and if you could repost your example ?
