Figure 13: Network to display an iso-surface in a data cube.

This network displays an iso-surface5 corresponding to some value in a data cube. The colour of the iso-surface varies to mimic the effect of light reflecting off the surface. The surface is plotted in its correct relative position inside a set of axes representing the edges of the data cube.
The network is shown in Figure 13.
histogram.net (see
Section 7) to find the minimum, maximum and distribution of values in the data.
Module ‘ShowBox’ extracts the bounding box of the data cube. ‘Isosurface’ computes the iso-surface and ‘AutoColor’ colours it. ‘Collect’ combines the bounding box and iso-surface.
5An iso-surface is the analogue in three-dimensional gridded data of a single contour in two-dimensional gridded data. That is, it is a surface defined by some constant value of the dependent variable.
