Look at vtkCutter and vtkPlane.  There are quite a few examples:

In graphics/examplesPython

combVol.py
cut.py
cutPlane.py
probe.py
rectGrid.py

or in graphics/examplesTcl

TestCopy.tcl
capCow.tcl
combVol.tcl
cut.tcl
cutCells.tcl
cutModel.tcl
cutPlane.tcl
fieldAttr2.tcl
fieldToRGrid.tcl
probe.tcl
rectGrid.tcl
