Re: Interpolating mapped values

Most high end CAD packages allow you to interpolate a complex surface
through point data - look for ones that are competent at surfacing.  Check
out CATIA - it will allow you to interpolate a surface, calculate the CofG
on a surface, and "cut" the surfaces into smaller pieces.  UG is another
good candidate.

With 3 points you can only define a plane, not a complex surface.  It sounds
like you are describing a tessellated surface.

If you have a tessellated surface you can use "postprocessor" software to
visualize the data and output contour plots.

Check out www.ceintl.com for examples of what I mean.  It's an excellent
software package.  This will allow you to plot your data.  You will still
need to calculate whatever it is you are trying to do.

If you are going all the way I'd suggest you write your own program to make
the calculations and then output the data to a good 3D plotting package like
Ensight above.  I highly recommend their excellent product.
