The NURBS Book
Les A. Piegl,Wayne Tiller +1 more
TL;DR: This chapter discusses the construction of B-spline Curves and Surfaces using Bezier Curves, as well as five Fundamental Geometric Algorithms, and their application to Curve Interpolation.
Journal ArticleDOI
On NURBS: a survey
TL;DR: The important characteristics of NURBS that have contributed to their wide acceptance as standard tools for geometry representation and design are summarized and their application to representing conic sections and commonly used surfaces, designing curves and surfaces, and modifying shapes is examined.
Journal ArticleDOI
Curve and surface constructions using rational B-splines
Les A. Piegl,Wayne Tiller +1 more
TL;DR: The non-uniform rational B-spline approximation (NUBA) as discussed by the authors is a unified approach to representing free-form as well as standard analytic curves and surfaces commonly used in CADCAM.

Ten challenges in 3D printing
William Oropallo,Les A. Piegl +1 more
TL;DR: The purpose of this paper is to paint a more realistic picture by identifying ten challenges that clearly illustrate the limitations of this technology, which makes it just as vulnerable as anything else that had been touted before as the next game changer.
