// .NAME vtkGenericCutter - cut a vtkGenericDataSet with an implicit function or scalar data
// .SECTION Description
// vtkGenericCutter is a filter to cut through data using any subclass of
// vtkImplicitFunction. That is, a polygonal surface is created
// corresponding to the implicit function F(x,y,z) = value(s), where
// you can specify one or more values used to cut with.
//
// In VTK, cutting means reducing a cell of dimension N to a cut surface
// of dimension N-1. For example, a tetrahedron when cut by a plane (i.e.,
// vtkPlane implicit function) will generate triangles. (In comparison,
// clipping takes a N dimensional cell and creates N dimension primitives.)
//
// vtkGenericCutter is generally used to "slice-through" a dataset, generating
// a surface that can be visualized. It is also possible to use
// vtkGenericCutter to do a form of volume rendering. vtkGenericCutter does
// this by generating multiple cut surfaces (usually planes) which are ordered
// (and rendered) from back-to-front. The surfaces are set translucent to give
// a volumetric rendering effect.
//
// This filter has been implemented to operate on generic datasets, rather
// than the typical vtkDataSet (and subclasses). vtkGenericDataSet is a more
// complex cousin of vtkDataSet, typically consisting of nonlinear,
// higher-order cells. To process this type of data, generic cells are
// automatically tessellated into linear cells prior to isocontouring.
