Suppose one needs to show multiple iso-surfaces
of one variable or Field in one display, such as temperature 
surfaces inside a thunderstorm.

The same ScalarMap is used  

sMap = new ScalarMap(vRealType, Display.IsoContour);

to map the data type to IsoContour for all surfaces.  
There is one ContourControl made from the ScalarMap. 
The command to change isosurface value is

 ContourControl.setSurfaceValue(surfaceValue);

When you call this to reset the value of one surface all
surfaces snap to that  value since there is one control.

Is there a way to achieve separate values for several isosurfaces
of the same field?

Might it be possible to use the other methods of ContourControl
such as setLevels(float[] levels, float base, boolean dash),
intended for lines, to use with surfaces?
