Thanks, L'Harmonieux, for the information.  I've seen various 3D contour
sofware packages perform some operations on a table of XYZ coordinates, and
produce interpolated mesh results.  For example, SigmaPlot, Surfer for
Windows, etc.  However, they provide no explanation as to their methods.

What if I wanted to 'fake' the connectivity info?  For example, choosing
between linearly connecting all the data points, or some non-linear fit.
Would it still be best to go the route of creating a scalar field?
