[vtkusers] Visualize 3D image (.mhd)

[Urvoas, Paul]

Hi,
I would like to visualize 3d mhd image with VTK, thanks to another program, I wrote the following code.
It crashes just after cout<<"caster ok" and I don't find my mistakes.

Thanks in advance,
Paul


int main(int argc, char* argv)
{

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

      vtkViewImage3D* view;

      cout << "start" <<endl;

      vtkMetaImageReader* reader = vtkMetaImageReader::New();
      reader->SetFileName ("Synthetic-04.mhd");
      reader->GetOutput()->Update();
      cout << "reader ok" <<endl;

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

      cout << "caster ok" <<endl;

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

      cout << "Copy volume to ImageOriaginale" <<endl;

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

      cout << "reader caster deleted" <<endl;

      int dims[3];
      ImageOriginale[0]->GetDimensions(dims);
      double spacing[3];
      ImageOriginale[0]->GetSpacing(spacing);
      cout << "spacing & dimension" <<endl;


  view->SetImage(ImageOriginale[0]);

  view->SetRenderingModeToVR();
  view->SetVolumeRayCastFunctionToMIP();

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


  view->SetImage (ImageOriginale[0]);
  view->SetRenderingModeToVR();
  view->SetVolumeRayCastFunctionToMIP();

  cout << "befor render" <<endl;
  renWin->Render();

}
