Textures

[Ron Inbar]

Hello Ana!

The input to the viewer is probably a 3D volume.  The method SetZSlice on
the viewer selects which 2D slice is visible.  The quickest solution,
therefore, is to use a vtkExtractVOI filter and SetVOI(0, 99, 0, 99, k, k)
where k is the number of the requested slice (available through
vtkImageViewer::GetZSlice()).
