Loren Eiseley (1907?77) is one of the most important American nature writers of the twentieth century and an admired practitioner of creative nonfiction. A native of Lincoln, Nebraska, Eiseley was a professor of anthropology and a prolific writer and poet who worked to bring an understanding of science to the general public, incorporating religion, philosophy, and science into his explorations of the human mind and the passage of time. As a writer who bridged the sciences and the humanities, Eiseley is a challenge for scholars locked into rigid disciplinary boundaries. Artifacts and Illuminations, the first full-length collection of critical essays on the writing of Eiseley, situates his work in the genres of creative nonfiction and nature writing. The contributing scholars apply a variety of critical approaches, including ecocriticism and place-oriented studies ranging across prairie, urban, and international contexts. Contributors explore such diverse topics as Eiseley?s use of anthropomorphism and Jungian concepts and examine how his work was informed by synecdoche. Long overdue, this collection demonstrates Eiseley?s continuing relevance as both a skilled literary craftsman and a profound thinker about the human place in the natural world.
A long-overdue publication that restores Wilfred to the art-historical canon Lumia presents a long-overdue reevaluation of the groundbreaking artist Thomas Wilfred (1889-1968), whose unprecedented works prefigured light art in America. As early as 1919, many years before the advent of consumer television and video technology, Wilfred began experimenting with light as his primary artistic medium, developing the means to control and project unique compositions of colorful, undulating light forms, which he referred to collectively as lumia. Manifested as both live performances on a cinematic scale and self-contained structures, Wilfred's innovative displays captivated audiences and influenced generations of artists to come. This publication, the first dedicated to Wilfred in over forty years, draws on the artist's personal archives and includes a number of insightful essays that trace the development of his work and its relation to his cultural milieu. Featuring a foreword by the celebrated artist James Turrell, Lumia helps to secure Wilfred's rightful place within the canon of modern art.
Islamic Art of Illumination presents an amazing mixture of classical Turkish illumination patterns and their contemporary interpretations. Sema Onat, a prominent illumination artist in Turkey, displays her incredible pieces of art, skillfully swirling her imagination together with classical Turkish Islamic patterns of illumination.
The City of Light. For many, these four words instantly conjure late nineteenth-century Paris and the garish colors of Toulouse-Lautrec’s iconic posters. More recently, the Eiffel Tower’s nightly show of sparkling electric lights has come to exemplify our fantasies of Parisian nightlife. Though we reflect longingly on such scenes, in Illuminated Paris, Hollis Clayson shows that there’s more to these clichés than meets the eye. In this richly illustrated book, she traces the dramatic evolution of lighting in Paris and how artists responded to the shifting visual and cultural scenes that resulted from these technologies. While older gas lighting produced a haze of orange, new electric lighting was hardly an improvement: the glare of experimental arc lights—themselves dangerous—left figures looking pale and ghoulish. As Clayson shows, artists’ representations of these new colors and shapes reveal turn-of-the-century concerns about modernization as electric lighting came to represent the harsh glare of rapidly accelerating social change. At the same time, in part thanks to American artists visiting the city, these works of art also produced our enduring romantic view of Parisian glamour and its Belle Époque.
In Gaming Matters, McAllister and Ruggill turn from the broader discussion of video game rhetoric to study the video game itself as a medium and the specific features that give rise to games as similar and yet diverse as Pong, Tomb Raider, and Halo.
This much needed, comprehensive and modern reference on display technology, illumination sources and color imaging focuses on visual effects and how reproduced images are best matched to human visual features. As such, it teaches readers how to exploit the knowledge of human color information processing to design usable, ergonomic, and pleasing displays or visual environments. The contents describe design principles and methods to optimize self-luminous visual technologies for the human user, including modern still and motion image displays, and indoor light sources. Design principles and methods are derived from the knowledge of the human visual system, with a special emphasis on color vision, color cognition, color harmony, color preference and visually evoked emotions. The expert authors include the most important and latest applications of the design principles and methods, forming a comprehensive view of human color information processing from the receptors through the retina via high-level visual perception right up to the level of cognition, preference, harmony, as well as visually evoked emotions. This book is included in the Wiley SID Series.
Irradiance caching is a ray tracing-based technique for computing global illumination on diffuse surfaces. Specifically, it addresses the computation of indirect illumination bouncing off one diffuse object onto another. The sole purpose of irradiance caching is to make this computation reasonably fast. The main idea is to perform the indirect illumination sampling only at a selected set of locations in the scene, store the results in a cache, and reuse the cached value at other points through fast interpolation. This book is for anyone interested in making a production-ready implementation of irradiance caching that reliably renders artifact-free images. Since its invention 20 years ago, the irradiance caching algorithm has been successfully used to accelerate global illumination computation in the Radiance lighting simulation system. Its widespread use had to wait until computers became fast enough to consider global illumination in film production rendering. Since then, its use is ubiquitous. Virtually all commercial and open-source rendering software base the global illumination computation upon irradiance caching. Although elegant and powerful, the algorithm in its basic form often fails to produce artifact-free mages. Unfortunately, practical information on implementing the algorithm is scarce. The main objective of this book is to show the irradiance caching algorithm along with all the details and tricks upon which the success of its practical implementation is dependent. In addition, we discuss some extensions of the basic algorithm, such as a GPU implementation for interactive global illumination computation and temporal caching that exploits temporal coherence to suppress flickering in animations. Our goal is to show the material without being overly theoretical. However, the reader should have some basic understanding of rendering concepts, ray tracing in particular. Familiarity with global illumination is useful but not necessary to read this book.
