accessing interpolated values of a slice from volumetric data

Support
1

I’m using pyVista to cut a slice from an unstructured grid. I believe the slice function in pyVista is using vtkCutter to create the slice. When I plot it, it shows an nice image floating in a 3d viewer. However I cant seem so access this data directly.

I can access the vertices on the sliced plane and their values. But I cant see how this is interpolated to produce the nice result that I’m seeing in the 3d Viewer.

Is there a way to access or replicate the interpolated image from the slice?

Thanks in advance!

Someone here might know about how to do this in PyVista (I don’t), but since that is a separate project build on top of VTK, you might ask in it’s discussion forum at pyvista/pyvista · Discussions · GitHub
