 * @class   vtkmContour
 * @brief   generate isosurface(s) from volume
 *
 * vtkmContour 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.
 *
 * @warning
 * This filter is currently only supports 3D 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.
