Isosurface: Double (+/-)

Add a double isosurface: just two isosurfaces at the same time, of different colors, through the same field. One isosurface corresponds with the chosen isovalue, the other one with the negative of that value.

The main control bar is identical to the control bar of a normal isosurface. If you show the details, you will find that in addition to the controls available for a normal isosurface, you can also specify coloring information. In this case, the two numbers for the HSV colors define the colors of the negative and positive isosurface.
