[vtkusers] How to display image sequence automatically?

[Fucang Jia]

Dear all,

   I encounter a question, I want to display many pieces of image using vtkImageData and vtkImageActor. But when I render them, only one image is displayed. How to display them automatically in a for cycle? Thanks a lot.  Here is my code in OnDraw(CDC* pDC):

  ....
vtkRenderer *ren = vtkRenderer::New();
vtkRenderWindow *renWin = vtkRenderWindow::New();
renWin->AddRenderer(ren);

vtkImageData *ImageData = vtkImageData::New();
     ImageData->SetScalarTypeToUnsignedChar();
     ImageData->SetExtent(0,255,0,2550,0);
    ImageData->AllocateScalars();
vtkImageActor *ImageActor = vtkImageActor::New();

 int i,j,k;
 for(i=0;i<72;i++){
      for(j=0;j<256;j++)
          for(k=0;k<256;k++)
              ImageData->GetPointData()->GetScalars()->SetTuple1(j*256+k, image[i][j][k]);
     ImageActor->SetInput(ImageData);
     ren->AddActor(ImageActor);
    renWin->Render();
}
