/**
* @class vtkFlyingEdgesPlaneCutter
* @brief cut a volume with a plane and generate a
* polygonal cut surface
*
* vtkFlyingEdgesPlaneCutter is a specialization of the FlyingEdges algorithm
* to cut a volume with a single plane. It is designed for performance and
* an exploratory, fast workflow.
*
* This algorithm is not only fast because it uses flying edges, but also
* because it plays some "tricks" during processing. For example, rather
* than evaluate the cut (plane) function on all volume points like vtkCutter
* and its ilk do, this algorithm intersects the volume x-edges against the
* plane to (potentially) generate the single intersection point. It then
* quickly classifies the voxel edges as above, below, or straddling the cut
* plane. Thus the number of plane evaluations is greatly reduced.
*
* For more information see vtkFlyingEdges3D and/or the paper "Flying Edges:
* A High-Performance Scalable Isocontouring Algorithm" by Schroeder,
* Maynard, Geveci. Proc. of LDAV 2015. Chicago, IL.
*
* @warning
* This filter is specialized to 3D volumes. This implementation can produce
* degenerate triangles (i.e., zero-area triangles).
*
* @warning
* This class has been threaded with vtkSMPTools. Using TBB or other
* non-sequential type (set in the CMake variable
* VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.
