### Description
Creates surfaces from labelled data. Volume data does not always contain samples of continuous data. A volume may contain discrete integer values, often the result of segmentation. This example smooths the discrete models generated by [vtkDiscreteMarchingCubes](http://www.vtk.org/doc/nightly/html/classvtkDiscreteMarchingCubes.html) with [vtkWindowedSincPolyDataFilter](http://www.vtk.org/doc/nightly/html/classvtkWindowedSincPolyDataFilter.html).
