I am trying to look at a sequence of image slices (like an MRI volume). I am using
the following pipeline..

vtkStructuredPoints-->vtkDataSetMapper-->vtkActor-->vtkXRenderWindow-->vtkXRenderWindowInteractor

I do this within a Motif interface with a scalar bar to control the slice being displayed.  It works,
but changing from slice to slice is very slow (SGI Indigo2). I had implemented this in GL inthe past
and it was very smooth.

Is there any way to improve the performance? I had not used the imaging pipeline, as I am not
sure how to display the results in a Window within the interface, whereas I know how to do it
with the 3D pipeline.

All that si done in this window is to be able to scroll through the slices, no other computation
is performed.

Thanks.
