[vtkusers] 3D Rendering of an sliced object

[OnezerO]

Dont work

I did that:
ConnectPipelines(m_itkExporter , m_vtkImporter );
m_vtkImporter->Update();     

vtkImageConstantPad  *m_vtkConstant = vtkImageConstantPad::New();
m_vtkConstant->SetInput( m_vtkImporter->GetOutput() );

vtkContourFilter *m_vtkContour = vtkContourFilter::New();
m_vtkContour->SetInput( m_vtkConstant->GetOutput() ); 

The 3d image obtained its equals to the previous one


You say i should try this extent thing ?

Hi OnezerO,

The filter vtkImageConstantPad is in the Imaging directory:
http://www.vtk.org/doc/nightly/html/classvtkImageConstantPad.html

int extent[6];
image->GetWholeExtent( extent )

extent[0]--;
extent[1]++;
extent[2]--;
extent[3]++;
extent[4]--;
extent[5]++;

vtkImageConstantPad *constantPad = vtkImageConstantPad::New();
constantPad->SetInput(image);
constantPad->SetOutputWholeExtent(extent);

vtkContourFilter *contourFilter = vtkContourFilter::New();
contourFilter->SetInput(constantPad->GetOutput());

Cheers,
Sylvain
