Hi Bill,
Two questions about this:
If i want to represent a surface is the same?
If the values of the domain are fixed values, can I add these values to a
Linear3DSet?
Many thanks,
Santi.

VisAD volume rendering only works if the domain Set of your
Field is a Linear3DSet. Perhaps that's the problem.

Hi Curtis,
I've done what you say and the result isn't what I expected. See the
attached image.
Cheers,
Santi.
