	Well, if you dont want to create a new class that does what
you wants you could make a custom LookupTable that does the job.  

<shameless plug>
If you use python you could use a Lookup table editor that I have
made.  It is part of vtk-cfd and is available at
	http://www.aero.iitm.ernet.in/~prabhu/vtk/vtk-cfd.html
if you want I could even mail you the script.  It uses Tkinter.
