// This example demonstrates how to use a vtkHyperOctreeSampleFunction and
// apply a vtkHyperOctreeCutter filter on it.
//
// The command line arguments are:
// -I        => run in interactive mode; unless this is used, the program will
//              not allow interaction and exit
// -D <path> => path to the data; the data should be in <path>/Data/

// If WRITE_RESULT is defined, the result of the surface filter is saved.
//#define WRITE_RESULT
