I'm guessing that we might be able to use what was learned in the whole tubular
function thread to rewrite the sphere sweep object code in triangle mesh form.

(Just because it would be cool, I'd like to see that hexagonal surface
tesselation used to cover surfaces, because the triangle mesh is just a subset
of that method)

Cousin Ricky and I have both manually converted text to splines.
Clipka was talking about converting all of the text to prisms.

I had been interested in creating lofting some time back, but never had the
opportunity to bite into that. (yet...  ;) )

Ah, libraries . . . and licenses.  :/

Very interested.
I've been wanting to do a user-controlled Voronoi pattern / object, and one of
the algorithms involves using a half-edge data structure.
