Graphics Shaders: Theory and Practice is intended for a second course in computer graphics at the undergraduate or graduate level, introducing shader programming in general, but focusing on the GLSL shading language. While teaching how to write programmable shaders, the authors also teach and reinforce the fundamentals of computer graphics. The second edition has been updated to incorporate changes in the OpenGL API (OpenGL 4.x and GLSL 4.x0) and also has a chapter on the new tessellation shaders, including many practical examples.

The book starts with a quick review of the graphics pipeline, emphasizing features that are rarely taught in introductory courses, but are immediately exposed in shader work. It then covers shader-specific theory for vertex, tessellation, geometry, and fragment shaders using the GLSL 4.x0 shading language. The text also introduces the freely available glman tool that enables you to develop, test, and tune shaders separately from the applications that will use them. The authors explore how shaders can be used to support a wide variety of applications and present examples of shaders in 3D geometry, scientific visualization, geometry morphing, algorithmic art, and more.

Features of the Second Edition:

• Written using the most recent specification releases (OpenGL 4.x and GLSL 4.x0) including code examples brought up-to-date with the current standard of the GLSL language.
• More examples and more exercises
• A chapter on tessellation shaders
• An expanded Serious Fun chapter with examples that illustrate using shaders to produce fun effects
• A discussion of how to handle the major changes occurring in the OpenGL standard, and some C++ classes to help you manage that transition

The authors thoroughly explain the concepts, use sample code to describe details of the concepts, and then challenge you to extend the examples. They provide sample source code for many of the book s examples at www.cgeducation.org

Sociological perspectives can be used to analyse societal and structural influences on human behaviour at individual, group and community levels. The authors link sociological concepts, debates and theories relating to key areas such as poverty, social exclusion, education, social class and social justice to develop your students' understanding of how sociological perspectives will impact upon their social work placements and practice. This book begins by taking students step-by-step through the ins and outs of why sociology is important to social work. It explains the relevance of sociology to everyday social work practice, introducing students to the core sociological perspectives that they'll need to get to grips with during their course, including functionalism, Marxism, symbolic interactionism and postmodernism. The book then moves on to explore various social issues in detail (i.e. poverty, social class, social exclusion, education, moral panics), with extended case studies, activities and links to skills in practice illustrating the many opportunities and challenges that each aspect brings to everyday practice. There are also important chapters on family, community and the role of sociology in social work training.

This book comes from an IFIP conference on computer graphics and education held in Spain in 1991. The aim of the conference was to bring together some of the most active people in the field internationally to - examine the current state of graphics technology for education - discuss how education is taking advantage of graphics - consider changes in educational systems to increase the use of graphics - project what graphics technologies will be available in five years for educational use. The book contains papers from speakers and participants in the conference as well as reports from conference working groups. The papers are devided into three groups: - multimedia and hypermedia - visual thinking and visualization - classroom experiences. The reader will get a good understanding of the breadth of opportunity offered by computer graphics as an educational tool, will see a number of current and emerging educational applications of graphics to education that challenge us to see graphics in our own teaching, and will have a better understanding of the direction graphics technologies are taking that can greatly increase the educational opportunities they offer.

Cystic fibrosis is the most common life-threatening inherited disease in the UK and Europe. It affects around 1 in 2500 live births in the UK. There have been enormous advances in the treatment of CF over the last 40 years, with life expectancy increasing from just 5 years in 1964 to mid 30s today, and it now affects as many adults as children. The burden of care for CF patients is, however, considerable, and with the increase in life expectancy the impact of CF on respiratory medicine has increased considerably.
Part of the Oxford Respiratory Medicine Library series, this pocketbook aims to be a concise companion for all health care professionals who manage, or come across, patients with CF. The book covers all aspects of care, including both paediatric and adult-specific issues. The book will appeal to a wide variety of health professionals in respiratory medicine, paediatrics, and primary care.

An understanding of social policy is crucial for social workers as it underpins and shapes the legislative framework that they work within. From safeguarding service users and enabling them to improve their lives, to protecting the most vulnerable in society, social policy also has a vital role to play within social work education. It is important therefore for students to engage critically with social policy. This book introduces policy and shows how it has changed and evolved over time, how it reflects changes in society and how it is applied to everyday practice.

Cystic Fibrosis (CF) is a multi-system disorder, requiring not just respiratory expertise but also management of nutrition, diabetes, musculoskeletal and psychosocial issues. This pocketbook is a concise companion for all health care professionals who manage patients with CF. The book covers all aspects of care, including both paediatric and adult-specific issues, and summarizes up-to-date literature in a concise and focussed style. There is an emphasis on the practical aspects of management with separate chapters covering the effects of CF in the lung, the microbiology of pulmonary CF, and management of exacerbations. Psychosocial aspects of CF care, end of life care and lung transplantation are also covered, and potential future therapies reviewed. This second edition has been extensively updated to reflect the UK CF Trust Standards of Care, treatment guidelines and Cochrane reviews. There are updates on emerging organisms; an expanded section on physiotherapy; and a new Pharmacopeia that covers all common CF medications.

Introduced 160 years ago as an attempt to generalize complex numbers to higher dimensions, quaternions are now recognized as one of the most important concepts in modern computer graphics. They offer a powerful way to represent rotations and compared to rotation matrices they use less memory, compose faster, and are naturally suited for efficient interpolation of rotations. Despite this, many practitioners have avoided quaternions because of the mathematics used to understand them, hoping that some day a more intuitive description will be available.
The wait is over. Andrew Hanson's new book is a fresh perspective on quaternions. The first part of the book focuses on visualizing quaternions to provide the intuition necessary to use them, and includes many illustrative examples to motivate why they are important-a beautiful introduction to those wanting to explore quaternions unencumbered by their mathematical aspects. The second part covers the all-important advanced applications, including quaternion curves, surfaces, and volumes. Finally, for those wanting the full story of the mathematics behind quaternions, there is a gentle introduction to their four-dimensional nature and to Clifford Algebras, the all-encompassing framework for vectors and quaternions.
* Richly illustrated introduction for the developer, scientist, engineer, or student in computer graphics, visualization, or entertainment computing.
* Covers both non-mathematical and mathematical approaches to quaternions.
* Companion website with an assortment of quaternion utilities and sample code, data sets for the book's illustrations, and Mathematica notebooks with essential algebraic utilities.
