Just after offering to jump into Farin's CAGD work on oscillating curves, I had a couple of papers that I am a co-author come back, and I have to focus on them. In addition, between work and personal stuff, I often received 100's of emails each day and sometimes things get misplaced... Can the person that posted their request for information on Farin's work reach out to me in a separate email off-list? It will probably be a week or more before I have time to pick this back up, and I would like to bounce some ideas and code back and forth before presenting anything publicly. Thanks and best regards, EBo --
