These are all regular VTK filters, which you can connect by calling something like this: `someFilter.SetInputConnection(someOtherFilter.GetOutputPort())`. You can learn fundamentals of VTK from the [VTK textbook](https://vtk.org/vtk-textbook/) and [VTK examples website](https://lorensen.github.io/VTKExamples/site/).
