Hi, I am searching for literature, fundamental articles etc., dealing with "NURBS" (Non Uniform Rational Beta Splines). Is there anybody who can help me? Please e-mail!

The paper was called: "Trimmed NURBS Surface Graphics Library Interface" I recall that there was a pretty clear description of the math involved. Also there were several bibliography entries, but I don't remember them precisely, here's some fragments though: A Practical Guide to Splines, deBoor(?) Springer(?) Curves & Surfaces for Computer Aided Geometric Design, Farin(?) also I think there is both a textbook and a magazine named "Computer Aided Geometric Design" - maybe a literature search using this phrase or "CAGD" and NURBS would turn up useful references.

Or look for things by Wolfgang Boehm or Bezier or Coons By the way, NURBS = NonUniformRational B-spline (as opposed to Beta splines) Hope this helps, Sarvajit Sinha, EECS dept, University of Michigan If you need more info, e-mail to sinha@caen.engin.umich.edu -- _________________________________________________________________________________ Sarvajit Sinha sinha@caen.engin.umich.edu University of Michigan _________________________________________________________________________________

Hello! I was wondering if anyone had some information on Non-Uniform Rational-B-Splines (or NURBS as they call them). I am embarking on a project that will be dealing with them quite a bit and need to locate some reference material. Most of the stuff that I have found deals with plain old B-splines, or Bezeir (sp) et al. I have located a copy of Wayne Tiller's '86 tutorial notes, Micheal E. Mortenson's Geometric Modeling, Fundementals of Interactive C.G., Fujio Yamaguchi's Curves and Surfaces in C.A.G.D., A survey of curve and surface methods in CAGD from CAGD written by Wolfgang Boehm (sp) and deBoors bible of B-splines. Do I have enough guns in my arsenal or is there a 'definitive reference' on the subject of NURBS? I will also eventually be making nice pictures with them (shading et al) and could use a good 'starting from scratch reference' on how to go about making those nice pictures that everyone googles at. I've also played with the IGES spec and some others. I have the basics, but I need info on things like 'blend surface' and 'fillet surface' et al. All of the difficult and time consuming tasks. 'Intersect NURBS' is another doozy... Thanks for any and all info!! tim@nwnexus.wa.com
