[vtkusers] vtkVolumeRayCastMapper shading

can someone offer generic advice, I am using the vtkVolumeRayCastMapper
for rendering a labelled volume. The resut is "edgy" and coarse when
shading is "on", not so when shading is "off". I assume this is due to
interpolation caused by shading, I do however like the more realistic
sharp look when the shading is on but would like to improve the rendered
image quality. What ways can I explore to get a good result.
For example Gouraud shading is available if I had a geometrical dataset but
this is not the case. How can I increase the look of the shading
interpolation or do I have to play around with adding different lighting
