VTK显示mhd,mha格式文件

下一篇文章将详细介绍mhd,mha文件的构成以及如何制作
void renderMhd () {
     // read input image
     vtkSmartPointer<vtkMetaImageReader > reader = vtkSmartPointer<vtkMetaImageReader >::New();
     reader->SetFileName ("HeadMRVolume.mhd");
     reader->Update ();

     vtkSmartPointer<vtkImageViewer2 > viewer = vtkSmartPointer<vtkImageViewer2 >::New();
     viewer->SetInputConnection (reader-> GetOutputPort());

     // render window
     vtkSmartPointer<vtkRenderWindowInteractor > renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor >::New();

     viewer->SetupInteractor (renderWindowInteractor);
     viewer->GetRenderer ()->ResetCamera();

     renderWindowInteractor->Initialize ();
     renderWindowInteractor->Start ();
}

显示效果就不用贴图了。
