I'm just trying to visualise a 3D volume of a 83 dicom series loaded using ITK by using VTKvolume but the scene generated is just a 3d cube with the series diplayed on top an bottom sides of the cube, how can I view the whole series in all the dimensions ?<br>----------------------------------------------<br>//configuiring VTk<br> vtkRenderer* renderer = vtkRenderer::New();<br><br> vtkRenderWindow* renWin = vtkRenderWindow::New();<br><br> renWin->AddRenderer(renderer);<br><br> vtkRenderWindowInteractor* iren = vtkRenderWindowInteractor::New();<br><br> iren->SetRenderWindow(renWin);<br><br><br><br> // Create transfer mapping scalar value to opacity<br><br> vtkPiecewiseFunction* opacityTransferFunction = <br> vtkPiecewiseFunction::New();<br><br> opacityTransferFunction->AddPoint(20.0,
