[vtkusers] Can't use vtkSliceCubes

[LinX]

Hi there.

I have tried to use the vtkSliceCubes filter, but I don't have a image series so
I can read them by using a vtkVolume16Reader.
I tried 
  vtkImageWriter *lWriter = vtkImageWriter::New();
  lWriter->SetInput( Image );
  lWriter->SetFilePrefix( "Images/Helix" );
  lWriter->SetFileDimensionality( 2 ); 
  lWriter->Write();

to write them, so I could 
  vtkVolume16Reader *v16 = vtkVolume16Reader::New();
  v16->SetDataDimensions(50,50);
  v16->SetImageRange(1,255);
  v16->SetDataByteOrderToLittleEndian();
  v16->SetFilePattern( "Images/Helix" );
  v16->SetDataSpacing(1, 1, 1);

and then 
  vtkSliceCubes *mcubes = vtkSliceCubes::New();
  mcubes->SetReader( v16 );
  mcubes->SetValue( 0 );
  mcubes->SetFileName( "fullHead.tri" );
  mcubes->SetLimitsFileName( "fullHead.lim" );
  mcubes->Update( );

  vtkMCubesReader *reader = vtkMCubesReader::New( );
  reader->SetFileName( "fullHead.tri" );
  reader->SetLimitsFileName( "fullHead.lim" );

but didn't worked. ( the "fullHead.lim" and "fullHead.tri"  are zero size files )

What am I doing wrong?




Thanx in advance
