Implicit and explicit forms are often referred to as nonparametric forms. This is a large area and cannot be covered completely in an intro­ ductory text. NURBS curves and surfaces are generalizations of both B-splines and Bézier curves and surfaces, the primary difference being the weighting of the control points, which makes NURBS curves rational. In the previous two sections we’ve looked at lines and planes in three dimensions (or \({\mathbb{R}^3}\)) and while these are used quite heavily at times in a Calculus class there are many other surfaces that are also used fairly regularly and … The figures are piecewise quadratic curves, each made up of three parabolic segments that are joined at the knot values (tick marks on the joints). 9/30/2003 15-462 Graphics I 2 Goals • How do we draw surfaces?
