I have absolutely no clue what you mean, sorry. When using
vtkImageViewer2 (vs vtkImageViewer) your 2D slice is displayed in the
3D world (as a texture), so the background is black by default. I
guess there should be an option to set it to something else ...

I think you can press 'c' to use camera mode instead of joystick mode.
This has been broken in VTK since > VTK 4.5 (AFAIK). Simply set
another interactor style that does not rely on the timer API.
