Is there a general algorithm to generate surface curves (such as NURBS) from
a two dimensional matrix of elevations?  The curves should only interpolate 
the reqion between data points and should *intersect* the data points.

I'm trying to get a feel for this problem - it this something I can get
a code fragment (or more) of - or is it research.

Feel free to followup via E-mail or by posting to this group. I'll be 
happy to summarize to the net.  (Should this be in the "commonly asked
questions" article?)
