Catoptric Anamorphosis on Free-Form Reflective Surfaces Francesco Di Paola, Pietro Pedone
7 / 2020 Catoptric Anamorphosis on Free-Form Reflective Surfaces Francesco Di Paola, Pietro Pedone Abstract The study focuses on the definition of a geometric methodology for the use of catoptric anamorphosis in contemporary architecture. The particular projective phenomenon is illustrated, showing typological-geometric properties, responding to mechanisms of light re- flection. It is pointed out that previous experience, over the centuries, employed the technique, relegating its realisation exclusively to reflecting devices realised by simple geometries, on a small scale and almost exclusively for convex mirrors. Wanting to extend the use of the projective phenomenon and experiment with the expressive potential on reflective surfaces of a complex geometric free-form nature, traditional geometric methods limit the design and prior control of the results, thus causing the desired effect to fail. Therefore, a generalisable methodological process of implementation is proposed, defined through the use of algorithmic-parametric procedures, for the determination of deformed images, describing possible subsequent developments. Keywords: anamorphosis, science of representation, generative algorithm, free-form, design.

De Divino Errore ‘De Divina Proportione’ Was Written by Luca Pacioli and Illustrated by Leonardo Da Vinci
De Divino Errore ‘De Divina Proportione’ was written by Luca Pacioli and illustrated by Leonardo da Vinci. It was one of the most widely read mathematical books. Unfortunately, a strongly emphasized statement in the book claims six summits of pyramids of the stellated icosidodecahedron lay in one plane. This is not so, and yet even extensively annotated editions of this book never noticed this error. Dutchmen Jos Janssens and Rinus Roelofs did so, 500 years later. Fig. 1: About this illustration of Leonardo da Vinci for the Milanese version of the ‘De Divina Proportione’, Pacioli erroneously wrote that the red and green dots lay in a plane. The book ‘De Divina Proportione’, or ‘On the Divine Ratio’, was written by the Franciscan Fra Luca Bartolomeo de Pacioli (1445-1517). His name is sometimes written Paciolo or Paccioli because Italian was not a uniform language in his days, when, moreover, Italy was not a country yet. Labeling Pacioli as a Tuscan, because of his birthplace of Borgo San Sepolcro, may be more correct, but he also studied in Venice and Rome, and spent much of his life in Perugia and Milan. In service of Duke and patron Ludovico Sforza, he would write his masterpiece, in 1497 (although it is more correct to say the work was written between 1496 and 1498, because it contains several parts). It was not his first opus, because in 1494 his ‘Summa de arithmetic, geometrica, proportioni et proportionalita’ had appeared; the ‘Summa’ and ‘Divina’ were not his only books, but surely the most famous ones. For hundreds of years the books were among the most widely read mathematical bestsellers, their fame being only surpassed by the ‘Elements’ of Euclid. -
Simple Rules for Incorporating Design Art Into Penrose and Fractal Tiles
Bridges 2012: Mathematics, Music, Art, Architecture, Culture Simple Rules for Incorporating Design Art into Penrose and Fractal Tiles San Le SLFFEA.com [email protected] Abstract Incorporating designs into the tiles that form tessellations presents an interesting challenge for artists. Creating a viable M.C. Escher-like image that works esthetically as well as functionally requires resolving incongruencies at a tile’s edge while constrained by its shape. Escher was the most well known practitioner in this style of mathematical visualization, but there are significant mathematical objects to which he never applied his artistry including Penrose Tilings and fractals. In this paper, we show that the rules of creating a traditional tile extend to these objects as well. To illustrate the versatility of tiling art, images were created with multiple figures and negative space leading to patterns distinct from the work of others. 1 1 Introduction M.C. Escher was the most prominent artist working with tessellations and space filling. Forty years after his death, his creations are still foremost in people’s minds in the field of tiling art. One of the reasons Escher continues to hold such a monopoly in this specialty are the unique challenges that come with creating Escher type designs inside a tessellation[15]. When an image is drawn into a tile and extends to the tile’s edge, it introduces incongruencies which are resolved by continuously aligning and refining the image. This is particularly true when the image consists of the lizards, fish, angels, etc. which populated Escher’s tilings because they do not have the 4-fold rotational symmetry that would make it possible to arbitrarily rotate the image ± 90, 180 degrees and have all the pieces fit[9]. -

Leonardo Da Vinci's Study of Light and Optics: a Synthesis of Fields in The
Bitler Leonardo da Vinci’s Study of Light and Optics Leonardo da Vinci’s Study of Light and Optics: A Synthesis of Fields in The Last Supper Nicole Bitler Stanford University Leonardo da Vinci’s Milanese observations of optics and astronomy complicated his understanding of light. Though these complications forced him to reject “tidy” interpretations of light and optics, they ultimately allowed him to excel in the portrayal of reflection, shadow, and luminescence (Kemp, 2006). Leonardo da Vinci’s The Last Supper demonstrates this careful study of light and the relation of light to perspective. In the work, da Vinci delved into the complications of optics and reflections, and its renown guided the artistic study of light by subsequent masters. From da Vinci’s personal manuscripts, accounts from his contemporaries, and present-day art historians, the iterative relationship between Leonardo da Vinci’s study of light and study of optics becomes apparent, as well as how his study of the two fields manifested in his paintings. Upon commencement of courtly service in Milan, da Vinci immersed himself in a range of scholarly pursuits. Da Vinci’s artistic and mathematical interest in perspective led him to the study of optics. Initially, da Vinci “accepted the ancient (and specifically Platonic) idea that the eye functioned by emitting a special type of visual ray” (Kemp, 2006, p. 114). In his early musings on the topic, da Vinci reiterated this notion, stating in his notebooks that, “the eye transmits through the atmosphere its own image to all the objects that are in front of it and receives them into itself” (Suh, 2005, p. -

Available from: www.prosoc.eu Selection and peer review under responsibility of Prof. Dr. Ayse Cakır Ilhan, Ankara University, Turkey. ©2017 SciencePark Research, Organization & Counseling. All rights reserved. Abstract Alternative approaches in illustration language have constantly been developing in terms of material and technical aspects. Illustration languages also differ in terms of semantics and form. Differences in formal expressions for increasing the effect of the subject on the audience lead to diversity in the illustrations. M. C. Escher’s three-dimensional images to be perceived in a two-dimensional environment, together with mathematical and symmetry-oriented studies and the systematic formed by a numerical structure in its background, are associated with the notion of illustration in terms of fictional meaning. Istvan Orosz used the technique of anamorphosis and made it possible for people to see their perception abilities and visual perception sensitivities in different environments created by him. This study identifies new approaches and illustration languages based on the works of both artists, bringing an alternative proposition to illustration languages in terms of systematic sub-structure and fictional idea sketches. -

More formally: a tessellation or tiling is a partition of the Euclidean plane into a countable number of closed sets called tiles, such that the tiles intersect only on their boundaries. These tiles may be polygons or any other shapes. Many tessellations are formed from a finite number of prototiles; all tiles in the tessellation are congruent to one of the given prototiles. If a geometric shape can be used as a prototile to create a tessellation, the shape is said to be able to tessellate or to “tile the plane”. Mathematicians have found no general rule for determining if a given shape can tile the plane or not, which means there are many unsolved problems concerning tessellations. -

Fractals: a Resonance Between Art and Nature
Fractals: A Resonance between Art and Nature Richard Taylor, Ben Newell, Branka Spehar and Colin Clifford Physics and Psychology Reveal the Fractal Secrets of Jackson Pollock’s Drip Paintings The discovery of fractal patterns was an interesting advance in the understanding of nature [1, 2]. Since the 1970s many natural scenes have been shown to be com- posed of fractal patterns. Examples include coastlines, clouds, lightning, trees, rivers and mountains. Fractal patterns are referred to as a new geometry because they look nothing like the more traditional shapes such as triangles and squares known within mathematics as Euclidean geometry. Whereas these shapes are composed of smooth lines, fractals are built from patterns that recur at finer and finer magnifications, generating shapes of immense complexity. Even the most common of nature’s fractal objects, such as the tree shown in Figure 1, contrast 53 sharply with the simplicity of artificially constructed objects such as buildings. But do people find such complexity visually appealing? In particular, given peo- ple’s continuous visual exposure to nature’s fractals, do we possess a fundamental appreciation of these patterns – an affinity independent of conscious delibera- tion? The study of human aesthetic judgement of fractal patterns constitutes a rela- tively new research field within perception psychology. Only recently has research started to quantify people’s visual preferences for (or against) fractal content. A useful starting point in assessing people’s ability to recognize and create visual pat- ternsistoexaminethemethodsusedbyartists to generate aesthetically pleasing images on their canvases. More specifically, in terms of exploring an intrinsic ap- preciation of certain patterns, it seems appropriate to examine the Surrealists and their desire to paint images which are free of conscious consideration. -
A Mathematical Analysis of Knotting and Linking in Leonardo Da Vinci's
November 3, 2014 Journal of Mathematics and the Arts Leonardov4 To appear in the Journal of Mathematics and the Arts Vol. 00, No. 00, Month 20XX, 1–31 A Mathematical Analysis of Knotting and Linking in Leonardo da Vinci’s Cartelle of the Accademia Vinciana Jessica Hoya and Kenneth C. Millettb Department of Mathematics, University of California, Santa Barbara, CA 93106, USA (submitted November 2014) Images of knotting and linking are found in many of the drawings and paintings of Leonardo da Vinci, but nowhere as powerfully as in the six engravings known as the cartelle of the Accademia Vinciana. We give a mathematical analysis of the complex characteristics of the knotting and linking found therein, the symmetry these structures embody, the application of topological measures to quantify some aspects of these configurations, a comparison of the complexity of each of the engravings, a discussion of the anomalies found in them, and a comparison with the forms of knotting and linking found in the engravings with those found in a number of Leonardo’s paintings. Keywords: Leonardo da Vinci; engravings; knotting; linking; geometry; symmetry; dihedral group; alternating link; Accademia Vinciana AMS Subject Classification:00A66;20F99;57M25;57M60 1. Introduction In addition to his roughly fifteen celebrated paintings and his many journals and notes of widely ranging explorations, Leonardo da Vinci is credited with the creation of six intricate designs representing entangled loops, for example Figure 1, in the 1490’s. Originally constructed as copperplate engravings, these designs were attributed to Leonardo and ‘known as the cartelle of the Accademia Vinciana’ [1].
