// .NAME vtkMarchingCubes - generate isosurface(s) from volume
// .SECTION Description
// vtkMarchingCubes is a filter that takes as input a volume (e.g., 3D
// structured point set) and generates on output one or more isosurfaces.
// One or more contour values must be specified to generate the isosurfaces.
// Alternatively, you can specify a min/max scalar range and the number of
// contours to generate a series of evenly spaced contour values.
// .SECTION Caveats
// This filter is specialized to volumes. If you are interested in
// contouring other types of data, use the general vtkContourFilter. If you
// want to contour an image (i.e., a volume slice), use vtkMarchingSquares.
