Do you want to show 4D-images?
vtk supports only 3D images. If you want to show the 4th dimension you
need to implement some trick.
You could try one of these solutions:
-stacking the 3rd and 4th dimension in the same dimension (the 3rd).
-depending of what you need exactly, another solution could be reading
the image under itk, extracting a 3D-volume and then exporting to vtk.
With this approach you lose some pipeline funcionality.
I have an application where I am showing 4D images. I read and process
the image on itk and I use vtk for visualization. I have developed some
classes to stack the 4th dimension in the 3rd before exporting to vtk,
preserving the pipeline update when a different t is needed.
