After much pondering, I have developed a suite of macros for working
with triangle meshes.  One of these macros will take a mesh of triangles
and calculate the smoothing normals required.  Another will perturb the
vertices of the mesh, making it rougher-looking.

However, the macro of interest is the divider, which takes a rough mesh
of large triangles and replaces it with a mesh of smaller triangles that
give a more curved appearance.  This process can be repeated, yielding
a fine mesh of triangles that simulate a large variety of curved
surfaces.  Its primary purpose is to allow a user to create a smooth
organic shape, containing many triangles, by defining a rougher mesh of
far fewer triangles, and refining that in an automated way.
