title A Description and Evaluation of Various 3-D Models
source IEEE Computer Graphics and Applications. January, 1984. vol. 4: pp. 38-52 : ill. Includes bibliography
summary The use of parametric curves and surfaces for object modeling in computer graphics is becoming increasingly popular. There is sometimes, however, a reluctance to use them because it seems that the added power they give is more than offset by the complexity of their formulations and their computations. The purpose of this article is to clarify their meanings and uses and show how much they have in common behind the diversity of their formulations. The author discusses the properties and benefits of using the parametric Hermite, Coons, Bezier, B-spline, and Beta-spline curve and surface formulations

title An Experimental Archaeology of CAD Using Software Reconstruction to Explore the Past and Future of ComputerAided Design
source Ji-Hyun Lee (Eds.) "Hello, Culture!"  [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, p. 130
summary This paper proposes software reconstruction as a method to shed new light into the material, gestural, and sensual dimensions of computer-aided design technologies. Specifically, it shows how by combining historical research and creative prototyping this method can bring us closer to distant ways of seeing, touching, drawing, and designing—while raising new questions about the impact of CAD technologies on present-day architectural practices. It documents the development of two software reconstructions—of Ivan Sutherland’s “Sketchpad” and of Steven A. Coons’s “Coons Patch”—and reflects on the responses they elicited in the context of two exhibitions. The paper shows how software reconstruction can offer access to overlooked aspects of computer-aided design systems, specially their material and sensual dimensions, and how we may explore its broader potential for research, preservation, pedagogy, and speculative design of design technologies.

title On Coons and Other Methods for the Representation of Curved Surfaces
source Computer Graphics and Image Processing. 1972. vol. 1: pp. 341-359 : ill. includes bibliography
summary Although Coons surfaces are mentioned frequently in the context of computer graphics and computer-aided design, very little of the work has been published. The purpose of this paper is to provide an up to date account of Coons methods and extensions thereof, drawing mainly on unpublished material. The subject is not approached from a rigorous mathematical point of view, which can be found elsewhere, but from the standpoint of the computer scientist or engineer who wishes to implement or use such methods. An extensive bibliography of the subject, including unpublished papers, is appended
keywords curved surfaces, representation, computer graphics, Coons

title Architectural Design Digital Change: Interactivity policy
source SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 1091-1097
summary Several researches have been focused on digital architecture historical perspectives of the design throughout the sixties. This paper purposes a different view based on the influence of art, science and computation in architecture that contributed to the use of interactivity in architectural design. The aim is to describe the evolution of interactive CAD from MIT’s Project CAD and Ivan Sutherland’s Sketchpad to the early digital architectural design pioneers: Steven Coons, Gyorgy Kepes and Nicholas Negroponte.

title Mathematical elements for computer graphics
source McGraw Hill, USA
summary The second edition of this classic computer graphics book represents a major rewrite. The clear concise discussion, the detailed algorithms, worked examples and numerous illustrations make the book of special interest to students, programmers and computer graphics professionals. The numerous detailed worked examples make it especially suitable for self-study. The first edition of the book, published in 1976, was one of the earliest computer graphics books. That first edition is still a staple on the bookshelves of many of the pioneers in computer graphics. The book thoroughly covers two- and three-dimensional transformations including rotation, scaling, translation, reflection, rotation about arbitrary points and axes, reflection about arbitrary lines and through arbitrary planes and points at infinity. Plane and space curves including efficient methods for representing conic sections, cubic splines, parabolically blended, Bezier and rational and non-rational B-spline (NURBS) curves are discussed. The discussion of surfaces includes surfaces of revolution, sweep surfaces, ruled and developable surfaces, Coons surfaces, Bezier and rational and non-rational B-splines (NURBS) surfaces. As with all the topics in the book, the discussion of both rational and non-rational B-spline curves and surfaces is accompanied by numerous detailed worked examples. The appendices contain over 50 pseudocoded algorithms including over 25 algorithms for Bezier and B-spline curves and surfaces.
