A book for those interested in how modern graphics programs work and how they can generate realistic-looking objects. It emphasises the mathematics behind computer graphics, most of which is included in an appendix. The main topics covered are: scan conversion methods; selecting the best pixels for generating lines, circles and other objects; geometric transformations and projections; translations, rotations, moving in 3D, perspective projections, curves and surfaces; construction, wire-frames, rendering, normals; CRTs, antialiasing, animation, colour, perception, polygons, compression. With its numerous illustrative examples and exercises, the book is ideal for a two-semester course for advanced undergraduates or graduates, while also making a fine reference for professionals in the field.
This book presents a broad overview of computer graphics (CG), its history, and the hardware tools it employs. Covering a substantial number of concepts and algorithms, the text describes the techniques, approaches, and algorithms at the core of this field. Emphasis is placed on practical design and implementation, highlighting how graphics software works, and explaining how current CG can generate and display realistic-looking objects. The mathematics is non-rigorous, with the necessary mathematical background introduced in the Appendixes. Features: includes numerous figures, examples and solved exercises; discusses the key 2D and 3D transformations, and the main types of projections; presents an extensive selection of methods, algorithms, and techniques; examines advanced techniques in CG, including the nature and properties of light and color, graphics standards and file formats, and fractals; explores the principles of image compression; describes the important input/output graphics devices.
Development and environment problems have reached such alarming proportions that the very survival of humanity is now subject to critical and unprecedented threats. In its latest report, the German Advisory Council on Global Change (WBGU) criticizes Germany's global change research community for its lack of international orientation, its bias towards individual disciplines and for its weaknesses in translating scientific results into a form readily accessible to policymakers. The Council identifies alternatives for restructuring the research landscape, focusing primarily on a new 'Syndrome Approach' for global change research. By applying this tool, scientists can systematically describe and analyze the 'diseases' afflicting the Earth System, and thus elaborate response options.
From the tragic young Adonis to Zašhapuna, first among goddesses, this handbook provides the most complete information available on deities from the cultures and religions of the ancient Near East, including Anatolia, Syria, Israel, Sumer, Babylonia, Assyria, and Elam. The result of nearly fifteen years of research, this handbook is more expansive and covers a wider range of sources and civilizations than any previous reference works on the topic. Arranged alphabetically, the entries range from multiple pages of information to a single line—sometimes all that we know about a given deity. Where possible, each record discusses the deity’s symbolism and imagery, connecting it to the myths, rituals, and festivals described in ancient sources. Many of the entries are accompanied by illustrations that aid in understanding the iconography, and they all include references to texts in which the god or goddess is mentioned. Appropriate for both trained scholars and nonacademic readers, this book collects centuries of Near Eastern mythology into one volume. It will be an especially valuable resource for anyone interested in Assyriology, ancient religion, and the ancient Near East.
Although we may not think we notice them, storefronts and their signage are meaningful, and the impact they have on people is significant. What the Signs Say argues that the public language of storefronts is a key component to the creation of the place known as Brooklyn, New York. Using a sample of more than two thousand storefronts and over a decade of ethnographic observation and interviews, the study charts two very different types of local Brooklyn retail signage. The unique and consistent features of many words, large lettering, and repetition that make up Old School signage both mark and produce an inclusive and open place. In contrast, the linguistic elements of New School signage, such as brevity and wordplay, signal not only the arrival of gentrification, but also the remaking of Brooklyn as distinctive and exclusive. Shonna Trinch and Edward Snajdr, a sociolinguist and an anthropologist respectively, show how the beliefs and ideas that people take as truths about language and its speakers are deployed in these different sign types. They also present in-depth ethnographic case studies that reveal how gentrification and corporate redevelopment in Brooklyn are intimately connected to public communication, literacy practices, the transformation of motherhood and gender roles, notions of historical preservation, urban planning, and systems of privilege. Far from peripheral or irrelevant, shop signs say loud and clear that language displayed in public always matters. This book is the recipient of the 2021 Norman L. and Roselea J. Goldberg Prize from Vanderbilt University Press for the best book in the area of art or medicine.
Requires only a basic knowledge of mathematics and is geared toward the general educated specialists. Includes a gallery of color images and Mathematica code listings.
This is the first English translation of Thomas Harriot’s seminal Artis Analyticae Praxis, first published in Latin in 1631. It has recently become clear that Harriot's editor substantially rearranged the work, and omitted sections beyond his comprehension. Commentary included with this translation relates to corresponding pages in the manuscript papers, enabling exploration of Harriot's novel and advanced mathematics. This publication provides the basis for a reassessment of the development of algebra.
