[vtkusers] 3D rendering with Meta image

[Urvoas, Paul]

Hi,
I wrote a program to visualize a mhd volume with a Vtk volume rendering window.
I don't get, I manage to compile and execute it but the window is empty, I cannot visualize my volume in.
(My mhd file is good..)

Any ideas ? Thanks in advance.

This is my code :

int main(int argc, char* argv)
{

vtkImageData** ImageOriginale  = new vtkImageData*[10];

      int i=0;
      while(i<10)
      {
             ImageOriginale[i]=vtkImageData::New();
            ++i;
      }

      vtkViewImage3D* view;
      view=vtkViewImage3D::New();

      cout << "start" <<endl;

      vtkMetaImageReader* reader = vtkMetaImageReader::New();
      reader->SetFileName ("FILTER.mhd");

      reader->GetOutput()->Update();
      cout << "reader ok" <<endl;

      vtkImageCast* caster = vtkImageCast::New();
      caster->SetInput (reader->GetOutput());
      caster->SetOutputScalarTypeToUnsignedShort ();
      caster->GetOutput()->Update();

      ImageOriginale[0]->DeepCopy(caster->GetOutput()) ;

      caster->Delete();
      reader->Delete();

      int dims[3];
      ImageOriginale[0]->GetDimensions(dims);
      double spacing[3];

      ImageOriginale[0]->GetSpacing(spacing);

      view->SetImage(ImageOriginale[0]);

      view->SetLinkZoom (true);
      view->SetBackgroundColor (255.0,0.0,0.0);

 // view->SetRenderingModeToVR();
  view->SetVolumeRayCastFunctionToMIP();
 // view->SetCubeVisibility(1);

  vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
  vtkRenderWindow *rwin = vtkRenderWindow::New();
  iren->SetRenderWindow ( rwin );
  vtkRenderer* ren = vtkRenderer::New();

  rwin->AddRenderer(ren);
  view->SetRenderWindow ( rwin );
  view->SetRenderer ( ren );

  rwin->Render();
  iren->Start();

  return 0;

}
