NonUniform Rational B-Splines (NURBS) are the standard for describing and modeling curves and surfaces in computer-aided design and computer graphics. These are used to model everything from automobile bodies and ship hulls to animated characters in feature-length films. Curves and surfaces are ...

Generating subdivision surfaces with curve interpolation constraints is needed in both computer graphics and geometric modeling applications. In the context of the Doo–Sabin subdivision scheme, this can be achieved through the use of polygonal complexes as suggested by Nasri (Presented at the Fifth Sia...

Basic techniques available for curves and surfaces begin to break down for threefolds, in particular because several fundamental constructions lead immediately to singular varieties, which are much more difficult to handle. However, since the 1980s, starting with the groundbreaking work of Mori, ...

3.1.1 Bézier curves and surfaces as images of normal curves and surfaces Rational Bézier curves are fundamental for geometric modeling. It is widely known that rational Bézier curves of degree two are conics. In fact, since polynomial Bézier curves of degree two are just parabolae, the desir...
