I want to intersect polydata and a plane. I can find `vtkIntersectionPolyDataFilter` to intersect two polydata.

Or I need to create a polydata from the plane?

Hello @zhang-qiang-github

you may look at the following classes, depending on expected output (cutted polydata, slice, intersection, etc.):

- [vtkPolyDataPlaneCutter](https://vtk.org/doc/nightly/html/classvtkPolyDataPlaneCutter.html#details)
- [vtkPlaneCutter](https://vtk.org/doc/nightly/html/classvtkPlaneCutter.html#details)
- [vtkFlyingEdgesPlaneCutter](https://vtk.org/doc/nightly/html/classvtkFlyingEdgesPlaneCutter.html#details)
