[vtkusers] vtkimagereader good working example in C?

[sbe]

Hi,

Any help is greatly appreciate. Thank you!

I have so much problem making work a good example for raw data display, I have tried many and this is the last one I have tried and it shows nothing? what's wrong with that? I'm using the data example of the head provides by vtk data examples, I have put all the files in the same directory as the executable!


 vtkRenderer *ren = vtkRenderer::New();
 vtkRenderWindow *ren_win = vtkRenderWindow::New();
 ren_win->AddRenderer(ren);
 vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
 iren->SetRenderWindow(ren_win);
 
 // read the volume
 vtkImageReader *reader = vtkImageReader::New();
 reader->SetDataExtent(0, 63, 0, 63, 1, 93);
 reader->SetDataByteOrderToLittleEndian();
 reader->SetFilePrefix("quarter");
 reader->SetDataSpacing(3.2, 3.2, 1.5);
 reader->SetDataScalarTypeToUnsignedShort();

 // extract the skin
 vtkContourFilter *skin_extractor = vtkContourFilter::New();
 skin_extractor->SetInput(reader->GetOutput());
 skin_extractor->SetValue(0, 500);

 vtkPolyDataMapper *skin_mapper = vtkPolyDataMapper::New();
 skin_mapper->SetInput(skin_extractor->GetOutput());
 skin_mapper->ScalarVisibilityOff();
 vtkActor *skin_actor = vtkActor::New();
 skin_actor->SetMapper(skin_mapper);
 
 // create the outline
 vtkOutlineFilter *outline = vtkOutlineFilter::New();
 outline->SetInput(reader->GetOutput());
 vtkPolyDataMapper *outline_mapper = vtkPolyDataMapper::New();
 outline_mapper->SetInput(outline->GetOutput());
 vtkActor *outline_actor = vtkActor::New();
 outline_actor->SetMapper(outline_mapper);
 outline_actor->GetProperty()->SetColor(1, 1, 1);

 // now, tell the renderer our actors  
 ren->AddActor(outline_actor);
 ren->AddActor(skin_actor);
 ren->ResetCamera();
 ren_win->SetSize(300, 300);
 iren->Start();
