Dear Ben,
I am interested in similar problems and I found your question interesting.
Since now I did not see any answer to your message on the forum; maybe they
have been posted to you directly. Could you forward them to me, or making from
them a collection?
We have in our lab a 3D solid modeling sofware which let us to interpolate
point in curves and curves in 3D surfaces. However, the real problem is that
when you collect points with a pointing device you get a "cloud" of points with
different density depending on the space position. If you try to generate a
surface from this cloud without any pre processing of the data, the chances of
getting a "good" surface will be quite low. Generally speaking, the density of
the mesh should be varying depending on the local curvatures of the surface.
So, it would be nice to find an algorithm (or a source code, much better!!)
able to read a cloud of points and generate a mesh with a such variable
density. This would give us the chance to generate the best mesh with the
minimum number of control points.
Being someway different from what you requested, I am cross posting this also
to the forum, to hear if anybody has suggestions on the topic.
