> Hi

> I have an application which was working with vtk2.4.
> Today I have installed the vtk3.1 and recompile my
> application. Then it doesn't work correctly anymore!
> 
> With vtk2.4 I have vtkStrucuturedPoints as the
> input for the vtkImageViewer. With vtk3.1 it doesn't
> like the vtkStructuredPoints as input. Ok, I have changed

> to use vtkImageData as the input for vtkImageViewer.
> Then I, instead of getting an image, just got a black
> viewer!
> 
> My scheme is something like the following:
> 
> First created a vtkScalars scalars;
> Then: 
> vtkImageData vol->SetDimensions(img.imgsize, img.imgsize, img.imgsize);
>              vol->SetOrigin(0., 0., 0.);
>              vol->SetSpacing(1.0, 1.0, 1.0);
>              vol->GetPointData()->SetScalars(scalars);
> vtkImageViewer viewer->SetInput(vol);
>                viewer->SetZSlice(index); 
>                vtkActor2D *imgActor = viewer->GetActor2D();
>                rend->AddActor2D(imgActor);
>                renW->Render();
> 
> Anyone can kindly point out why it doesn't work anymore?
> As I said, it worked fine with vtk2.4(with StructuredPoints instead of
> ImageData)!
