I think I am missing something here... if I do what you suggest, I will
be mapping the DATA VALUES on the isosurface, right? But what I want to
map is the VOXEL POSITION. How can I feed this to the color module? I
tried with Compute, but couldn't figure out how.
Thanks,

Oh sorry. I knew I shouldn't have replied til the Mon morning coffee
soaked in deeper.
Mark("positions"). This makes the positions the 'data' (preserves the
'data' in 'saved data').
Now compute the distance vector (sqrt(a.x*a.x + a.y*a.y + a.z*a.z)) in Compute.
Colormap this 'data'.
If you need to recover your 'saved data' for some other purpose (like
if you haven't done the Isosurface yet), there are a couple tricks.
You do NOT want to Unmark because the distance vector values will
become (overwrite) the previous positions and screw the field up.
Trick 1: So I might suggest Unmark("junk") followed by Remove("junk")
as the easiest way. The Unmark is often required to counterbalance a
Mark, in case you need another Mark downstream. If you don't need to
work with the data after the Color operation, you can skip both the
Unmark and Remove steps.
Trick 2: Another way to do this is to Replace the colors from the
colored field onto the original field (prior to Mark) as the colors
of that field.
