T-Splines is the culmination of a career of research in the field of computer-aided geometric design by Dr. Thomas W. Sederberg. We present here some of his notes on the subjects of Bezier curves, NURBS, and related topics that he wrote for university courses he has taught. Please feel free to use them on your websites, in your own courses, or as a personal reference. If you republish them on the web or otherwise, we ask that you credit Dr. Sederberg and provide a link back to this page.
