OK, I think this makes sense. Use an Integer1DSet as my domain (index)
and map each Irregular2DSet to the domain. (index -> Set(x,y)).
But how is this done since a FunctionType requires (MathType, MathType)
and what we have above is (MathType, ThingImpl)? Can I wrap the Set in
a RealTupleType which is a MathType?
Also, how do I get the colors involved? Do I make r, g, and b RealTypes
and give them values as a RealTuple and map them to ScalarMaps?
VisAD keeps me humble! ;-)
Thanks!
