[vtkusers] 3D Rendering of an sliced object

[OnezerO]

 Sylvain,
This is the result using the code you give me

This is the code

ConnectPipelines(m_itkExporter , m_vtkImporter );
m_vtkImporter->GetWholeExtent( extent );
m_vtkImporter->Update();     

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

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

Thanks for your help!

Hi OnezerO,

Could you try the code I sent you in my previous email (see below)?

Cheers,
Sylvain
