#include <vtkDiscreteMarchingCubes.h>
takes as input a volume (e.g., 3D structured point set) of segmentation labels and generates on output one or more models representing the boundaries between the specified label and the adjacent structures. One or more label values must be specified to generate the models. The boundary positions are always defined to be half-way between adjacent voxels. This filter works best with integral scalar values. If ComputeScalars is on (the default), each output cell will have cell data that corresponds to the scalar value (segmentation label) of the corresponding cube. Note that this differs from vtkMarchingCubes, which stores the scalar value as point data. The rationale for this difference is that cell vertices may be shared between multiple cells. This also means that the resultant polydata may be non-manifold (cell faces may be coincident). To further process the polydata, users should either: 1) extract cells that have a common scalar value using vtkThreshold, or 2) process the data with filters that can handle non-manifold polydata (e.g. vtkWindowedSincPolyDataFilter). Also note, Normals and Gradients are not computed.

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
