Hello all, A little while ago, Richard Bartels posted an algorithm that calculated the deBoor-Cox recurrance relation, and gave a method for calculating b-spline curves based on the algorithm. I have had some problems generalizing the use of the evaluation algorithm to include NURBS patches. If someone out there can flip my light switch (so to speak), I would be most appreciative. As of today's date, I am calculating b-splines the old fashioned way. I call deBoor-Cox recursively and compute a summation. This is tediously slow. I am just starting with curves and surfaces, and also would like to know if people have a preference as to the "best" book for curve and surface basics. I have Farin, and Bartels, and can't decide which one to start to churn through. -Jeff Nimeroff .nosig
