Well, you may have already tried this but cant you use the
vtkWarpScalar class?  Look at the following:

in graphics/examplesPython

$ grep -l warp *
blow.py
dispPlot.py
expCos2.py
imageWarp.py
rectGrid.py
smoothCyl.py
spToPd.py
velProf.py
vib.py
warpComb.py
$

I think expCos2.py looks something like what you might want.  There
are similar examples in Tcl also.

Hope this helps.
prabhu
