plotting 3-d surface from data in irregular set

["Susanna Ricco" <smricco@xxxxxxxxxx>]

I have a set of values generated by a surface fitting program that I 
want to view as a 3-d surface. The MathType is ((x,y)-> z). I'm using an 
irregular set for the domain created with an array of floats from the 
data generated by the surface fitter. I can plot the data as points, but 
I can't figure out how to get VisAD to connect the points and create a 
surface. I've tried looking at the examples, but none of them use 
irregular sets. Is it not possible to plot a surface from an irregular 
set? I'm pretty sure I have to use an irregular set because the points 
from the surface fitter aren't guaranteed to be at regular intervals.

Thanks for the help,
