Mirrors and Reflections


Book Description

This graduate/advanced undergraduate textbook contains a systematic and elementary treatment of finite groups generated by reflections. The approach is based on fundamental geometric considerations in Coxeter complexes, and emphasizes the intuitive geometric aspects of the theory of reflection groups. Key features include: many important concepts in the proofs are illustrated in simple drawings, which give easy access to the theory; a large number of exercises at various levels of difficulty; some Euclidean geometry is included along with the theory of convex polyhedra; no prerequisites are necessary beyond the basic concepts of linear algebra and group theory; and a good index and bibliography The exposition is directed at advanced undergraduates and first-year graduate students.




Mirrors and Mirroring from Antiquity to the Early Modern Period


Book Description

This volume examines mirrors and mirroring through a series of multidisciplinary essays, especially focusing on the intersection between technological and cultural dynamics of mirrors. The international scholars brought together here explore critical questions around the mirror as artefact and the phenomenon of mirroring. Beside the common visual registration of an action or inaction, in a two dimensional and reversed form, various types of mirrors often possess special abilities which can produce a distorted picture of reality, serving in this way illusion and falsehood. Part I looks at a selection of theory from ancient writers, demonstrating the concern to explore these same questions in antiquity. Part II considers the role reflections can play in forming ideas of gender and identity. Beyond the everyday, we see in Part III how oracular mirrors and magical mirrors reveal the invisible divine – prosthetics that allow us to look where the eye cannot reach. Finally, Part IV considers mirrors' roles in displaying the visible and invisible in antiquity and since.

The Art of Perspective


Book Description

Everything you need to know to put your drawings and paintings into perspective! If the concept of perspective makes you think of confusing angles, fancy measuring gadgets and complicated theories, get ready for a very pleasant surprise. In this comprehensive guide, Phil Metzger demystifies perspective, presenting it simply as a matter of mimicking the way we see--like the way a distant mountain appears blue, or a road seems to narrow in the distance. The Art of Perspective offers simple but powerful techniques for achieving a convincing illusion of depth and distance, whether it's a few inches in a still life or miles in a landscape. • Start simple, with atmospheric perspective and intuitive techniques, and gradually progress to linear perspective and more complex challenges such as stairways, curves and reflections. • Use the engaging, step-by-step demonstrations and exercises to try out each essential concept for yourself, making lessons clearer and more memorable. • Learn theories that apply to all mediums, with specific advice for achieving effects using acrylic, oil, watercolor and pencil. • Get the inside scoop on professional tricks and shortcuts that make perspective easier than ever! Forget everything you think you know (or don't know) about perspective. This book builds an easy-to-follow, ground-up understanding of how to turn a flat painting or drawing surface into a living, breathing, dimensional scene that lures viewers in. No matter how you look at it, it's the ultimate guide to perspective for artists of every medium and skill level.

The Visual World of Shadows


Book Description

How the perception of shadows, studied by vision scientists and visual artists, reveals the inner workings of the visual system. In The Visual World of Shadows, Roberto Casati and Patrick Cavanagh examine how the perception of shadows, as studied by vision scientists and visual artists, reveals the inner workings of the visual system. Shadows are at once a massive problem for vision—which must distinguish them from objects or material features of objects—and a resource, signaling the presence, location, shape, and size of objects. Casati and Cavanagh draw up an inventory of information retrievable from shadows, showing their amazing variety. They present an overview of the visual system, distinguishing between measurement and inference. They discuss the shadow mission, the work done by the visual brain to parse, and perhaps discard, the information from shadows; shadow ownership, the association of a shadow with the object that casts it; shadow labeling, the visual system's ability to tell shadows from nonshadows; and the shadow concept, our knowledge about shadows as a category. Casati and Cavanagh then apply the theoretical apparatus they have developed for shadows to other phenomena: illumination, reflection, and transparency. Finally, they examine the art of the shadow, paying tribute to artists' exploration of shadow, analyzing a series of artworks (reproduced in color) from a rich and fascinating art historical corpus.
