Here is an example of clipping by a plane:

[https://examples.vtk.org/site/Cxx/UnstructuredGrid/ClipUnstructuredGridWithPlane/](https://examples.vtk.org/site/Cxx/UnstructuredGrid/ClipUnstructuredGridWithPlane/)

VTK follows a data pipeline model, so to “unclip” the dataset just means removing the clipping filter and using the original mesh instead.
