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.

The eleven chapters in this international volume draw on a variety of theoretical and methodological approaches to focus our attention on medieval and early modern things (ca. 700–1600). The range of things includes actual objects (the Altenburg Crucifixion, a copy of Hieronymus Brunschwig’s Liber de arte distillandi, a pilgrim’s letter), imagined objects (a prayed cloak for the Virgin Mary), and narrative objects in texts (the Alliterative Morte Arthure, the Ordene de Chevalerie, Hartmann von Aue’s Erec, Heinrich of Neustadt’s Apollonius of Tyre, Luís de Camões’s Os Lusíadas, and the vita of Saint Guthlac). Each in its own way, the papers consider how things do what they do in texts and art, often foregrounding the intersection between the material and the immaterial by exploring such questions as how things act, how they express power, and how texts and images represent them. Medieval and early modern things are repeatedly shown to be more than symbolic or passive, they are agentive and determinative in both their intra- and extradiegetic worlds. The things that are addressed in this volume are varied and are embedded, or entangled, in different contexts and societies, and yet they share a concerted engagement in human life.

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.

The illumination of African philosophy offered in this volume leads to the illumination of philosophy in general. Illuminating arises as an essential task of philosophy, whether African or not. What is illuminated is not already there, but is constituted at the moment of illumination. This book invites the reader to participate in the illuminating work of philosophy and necessarily, thereby, to contribute to his or her own self-constituting self-illumination. Although the focus is on African philosophy, the book also bridges the gap between African philosophy and other branches. Today more than ever, a bridging philosophy is called for, and this book helps to meet that need. This book poses philosophical questions such as who is an African and what Africa is, and seeks philosophical answers. In doing so, it contributes to the ongoing discourse on African philosophy. It addresses such issues as the African grounding of philosophy, the difference between African and Black philosophy, the African body, African art as expressed in and by Chiwara, the plight of African trees as the plight of Africans, and the symbolic meaning of Robben Island.

This book presents techniques to render photo-realistic images by programming the Graphics Processing Unit (GPU). We discuss effects such as mirror reflections, refractions, caustics, diffuse or glossy indirect illumination, radiosity, single or multiple scattering in participating media, tone reproduction, glow, and depth of field. The book targets game developers, graphics programmers, and also students with some basic understanding of computer graphics algorithms, rendering APIs like Direct3D or OpenGL, and shader programming. In order to make the book self-contained, the most important concepts of local illumination and global illumination rendering, graphics hardware, and Direct3D/HLSL programming are reviewed in the first chapters. After these introductory chapters we warm up with simple methods including shadow and environment mapping, then we move on toward advanced concepts aiming at global illumination rendering. Since it would have been impossible to give a rigorous review of all approaches proposed in this field, we go into the details of just a few methods solving each particular global illumination effect. However, a short discussion of the state of the art and links to the bibliography are also provided to refer the interested reader to techniques that are not detailed in this book. The implementation of the selected methods is also presented in HLSL, and we discuss their observed performance, merits, and disadvantages. In the last chapter, we also review how these techniques can be integrated in an advanced game engine and present case studies of their exploitation in games. Having gone through this book, the reader will have an overview of the state of the art, will be able to apply and improve these techniques, and most importantly, will be capable of developing brand new GPU algorithms.

Computer Vision Metrics provides an extensive survey and analysis of over 100 current and historical feature description and machine vision methods, with a detailed taxonomy for local, regional and global features. This book provides necessary background to develop intuition about why interest point detectors and feature descriptors actually work, how they are designed, with observations about tuning the methods for achieving robustness and invariance targets for specific applications. The survey is broader than it is deep, with over 540 references provided to dig deeper. The taxonomy includes search methods, spectra components, descriptor representation, shape, distance functions, accuracy, efficiency, robustness and invariance attributes, and more. Rather than providing ‘how-to’ source code examples and shortcuts, this book provides a counterpoint discussion to the many fine opencv community source code resources available for hands-on practitioners.

In 2009, for the second time in a row, Jena hosted an extraordinary event. In th 2008, Jena celebrated the 450 birthday of the Friedrich Schiller University of Jena with the motto “Lichtgedanken” – “?ashes of brilliance. ” This year, for almost one week, Jena became the center for the pattern recognition research st community of the German-speaking countries in Europe by hosting the 31 Annual Symposium of the Deutsche Arbeitsgemeinschaft fur ¨ Mustererkennung (DAGM). Jena is a special place for this event for several reasons. Firstly, it is the ?rst time that the university of Jena has been selected to host this conference, and it isanopportunitytopresentthecityofJenaaso?eringafascinatingcombination of historic sites, an intellectual past, a delightful countryside,and innovative, - ternationalresearchandindustrywithinThuringia. Second,the conferencetakes place in an environment that has been heavily in?uenced by optics research and industry for more than 150 years. Third, in several schools and departments at the University of Jena, research institutions and companies in the ?elds of p- tern recognition, 3D computer vision, and machine learning play an important role. The university's involvement includes such diverse activities as industrial inspection, medical image processing and analysis, remote sensing, biomedical analysis, and cutting-edge developments in the ?eld of physics, such as the - cent development of the new terahertz imaging technique. Thus, DAGM 2009 was an important event to transfer basic research results to di?erent appli- tions in such areas.

The literary-philosophical works of Walter Benjamin (1892-1940) rank among the most quietly influential of the post-war era, though only since his death has Benjamin achieved the fame and critical currency outside his native Germany accorded him by a select few during his lifetime. Now he is widely held to have possessed one of the most acute and original minds of the Central European culture decimated by the Nazis. Illuminations contains his two most celebrated essays, 'The Work of Art in the Age of Mechanical Reproduction' and 'Theses on the Philosophy of History', as well as others on the art of translation, Kafka, storytelling, Baudelaire, Brecht's epic theatre, Proust and an anatomy of his own obsession, book collecting. The essay is Benjamin's domain; those collected in this now legendary volume offer the best possible access to his singular and significant achievement. In a stimulating introduction, Hannah Arendt reveals how Benjamin's life and work are a prism to his times, and identifies him as possessing the rare ability to think poetically.
