Dan-

Sorry for the delay in responding to this.  We've been trying
to get the release out.

From that method you should get something that is either:

(x,y,z) -> (value)

or

(Time -> ((x,y,z) -> (value)))  (for a time sequence)

What format do you want to pass to your applet in the end (z->value)?

FieldImpl.toString() will print out the range values.  There's not
a real good method to print out the domain values, but you could get
the domain set with GridUtil.getSpatialDomain(FieldImpl).

I'm going to be out the rest of the day, but let me know in
more detail what you want to pass in and I'll get back to you
on Monday.
