Hi Paul --
If your function has no logic that needs to be applied to each point,
then if the data were read in via the IDV they would be "VisAD Data
objects" and you should just be able to do something like:
a = b + c - d
where "b", "c" and "d" are 3D Data objects (or maybe 4D if they
include "time") and it will do the computation on every point. and put
the result in "a" (creating a new Data object with characteristics
like that of "b" (the first object in the computation).
If you have logic, then you might have to iterate over every point...I
say "might" because sometimes some of the built-in methods like "mask"
can be used to simulate logic.
Hope that helps.
