Cut vtkHyperOctree with user-specified implicit function.
vtkHyperOctreeCutter 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.)
vtkHyperOctreeCutter is generally used to "slice-through" a dataset, generating a surface that can be visualized. It is also possible to use vtkHyperOctreeCutter to do a form of volume rendering. vtkHyperOctreeCutter 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.
Note that data can be cut using either 1) the scalar values associated with the dataset or 2) an implicit function associated with this class. By default, if an implicit function is set it is used to cut the data set, otherwise the dataset scalars are used to perform the cut.

Set the sorting order for the generated polydata. There are two possibilities: Sort by value = 0 - This is the most efficient sort. For each cell, all contour values are processed. This is the default. Sort by cell = 1 - For each contour value, all cells are processed. This order should be used if the extracted polygons must be rendered in a back-to-front or front-to-back order. This is very problem dependent. For most applications, the default order is fine (and faster). Sort by cell is going to have a problem if the input has 2D and 3D cells. Cell data will be scrambled becauses with vtkPolyData output, verts and lines have lower cell ids than triangles.
