[vtkusers] Fwd: Re: vtkDICOMImageReader 3D render

[sercani]

  What kind of a 3D rendering do you want? MPR, MIP, MINIP, SSD, VRT?
For example for SSD rendering you can try this:

     vtkMarchingContourFilter *contour=vtkMarchingContourFilter::New();
     contour->SetInput(reader->GetOutput());
     contour->SetValue(0,-500);
     contour->Update();

     vtkStripper *stripper=vtkStripper::New();
     stripper->SetInput(contour->GetOutput());

     vtkPolyDataMapper *polyDataMapper=vtkPolyDataMapper::New();
     polyDataMapper->SetInput(stripper->GetOutput());
     polyDataMapper->ScalarVisibilityOff();

     vtkProperty *prop=vtkProperty::New();
     prop->SetColor(1,1,0.940);
     prop->ShadingOn();
     prop->BackfaceCullingOff();

     vtkActor *actor=vtkActor::New();
     actor->SetMapper(polyDataMapper);
     actor->SetProperty(prop);
     actor->RotateX(90.0);
     actor->VisibilityOn();

     qvtk->GetRenderer()->AddActor(actor);
     qvtk->GetRenderer()->ResetCameraClippingRange();

     contour->Delete();
     stripper->Delete();
     polyDataMapper->Delete();
     prop->Delete();
