Hi Tim
An easy way would be to define a separate RealType for each
number of IsoSurfaces, each representing the same range
values:
(x,y,z) -> (RealType1, RealType2, RealTypeN)
Then map:
RealType1 -> IsoContour
RealType2 -> IsoContour
RealTypeN -> IsoContour
This would waste memory, but you could try reusing the
domainSet in separate FlatFields using the
FlatField.setSamples(float[][] range, boolean copy) with
copy == false.
For a couple of isosurfaces, I wouldn't think this would be
to bad.
