I have the following problem:

The surface of a three-dimensional biological object has been
measured by measuring the (three-dimensional) coordinates of several hundred

The points were chosen from curves on the surface, but the
number, position, and length of the curves is irregular.

I would like to generate a triangulation of the surface
so that it can be displayed, and would then like to
carry out further computations, such as calculating
the normal to the surface.

Suggestions about suitable software would be welcome.

In particular, is there software available which can generate a
triangulation of a surface given a list of points on the
