The network is shown in Figure .

Figure: Network to display an iso-surface in a data cube.

• To specify the data cube to be read double-click on the `Import' module and follow the instructions in Section .

• To specify the value for the iso-surface double-click on the `Scalar' module at the top of the network and enter the required value. If you have no knowledge of the range of values in the cube, and hence no idea of suitable value, use network histogram.net (see Section ) to find the minimum, maximum and distribution of values in the data.
