Rational Bézier and B-Spline Curves
Rational B-spline curves1 have become the standard curve and surface description in the field of CAD and graphics. The use of rational curves in CAGD may be traced to Coons [124], [126], and Forrest [240]. By now, there are books on NURBS: Fiorot and Jeannin [233], Farin [202], Piegl and Tiller [482].
13.1 Rational Bézier Curves
In Chapter 12, we obtained a conic section in 
as the projection of a parabola (a quadratic) in 
. Conic sections may be expressed as rational quadratic (Bézier) curves, and their generalization ...
