[vtkusers] display a thick shell of volume

Hi VTK users,
I want to volume render (using 3D texture mapper) a shell with specified
thickness. Previously, I used vtkClipVolume twice, one clipped away the
inner portion of a regular volume data, the other clipped away outer
portion. The only problem is slow rendering speed because the resultant
data is no longer a regular volume data.
Can anyone suggest a better solution? Would it be faster if I used
several spheres with texture mapped on them and alpha-blending? Thanks.
