Excellent work! I have been looking into curve rendering myself lately, and found some links that you might find interesting (besides the Loop/Blinn article Bob already forwarded to you)

Hey! I showed that article to Bob, not the other way around. Mind you, he was already aware of the technique, of course.

Oh, I also told Bob about that article, which is published in GPU GEMS 3. I must have misunderstood. It is of course a very famous article ( but the technique is patented :| )

It would be interesting to know whether or not the patent is aggressively enforced. I don't know if anyone (Conal?) has contacts who would know.
