David,
     Thanks!  sorry, i also do not know why the image was disappeared.   I
don't know whether the problem is related to the code. Because the same code
can applied in other images(dataset), and the problem did not occurred. The
related code was presented:

   m_read = new vtkBMPReader();
   skinExtractor = vtkMarchingCubes::New();//
   skinNormals = vtkPolyDataNormals::New();//
    triangle=vtkTriangleFilter::New();//
    deci=vtkDecimatePro::New();/
    smoother=vtkSmoothPolyDataFilter::New();//
    skinMapper = vtkPolyDataMapper::New();//
    skin = vtkActor::New();

    this->m_read->Update();//read the bmp image
    this->skinExtractor->SetInputConnection(m_read->GetOutputPort());
    this->skinExtractor->SetValue(0,threshshold);
    this->skinNormals->SetInputConnection(skinExtractor->GetOutputPort());/
    this->skinNormals->SetFeatureAngle(60.0);//
    this->triangle->SetInputConnection(skinNormals->GetOutputPort());//
    this->deci->SetInputConnection(triangle->GetOutputPort());//
    this->deci->SetTargetReduction(predigestion);//
    this->deci->PreserveTopologyOn();//
    this->smoother->SetInputConnection(deci->GetOutputPort());//
    this->smoother->SetNumberOfIterations(smoothness);//
    this->skinMapper->SetInputConnection(smoother->GetOutputPort());//
    this->skinMapper->ScalarVisibilityOff();//
    this->skinMapper->SetColorModeToMapScalars();
    this->skinMapper->SetScalarRange(-1,1);


    // Link the actor

    this->skin->SetMapper(this->skinMapper);
    this->skin->GetProperty()->SetColor(0.94,0.83,0.45);


The image of the result:

[image: 5.bmp]

Thanks!

Please keep the discussion on the mailing list so everyone can benefit/help.

Thanks,

David
