The night the first Mars Exploration Rover landed, the engineering team at the Jet Propulsion Laboratory in Pasadena excitedly announced: ´´We have excellent quaternions for the rover!´´ This meant that through the application of a technique developed 160 years before they were able to determine the precise orientation of the spacecraft on Mars after traveling millions of miles through space. Quaternions are widely used in computer graphics, simulations, Hollywood special effects, computer games, and space travel, but they are conceptually very hard to grasp. The computer graphics community has a general familiarity with quaternions and their uses, but there are still many unresolved issues and controversies with them. And the subject mystifies many new engineers, such as game developers who lack a background in mathematics. While there are books that approach quaternions from a mathematician´s perspective, this is the first that will give a professional developer an intuitive understanding of quaternions through visual representations. Visualizing Quaternions introduces new developers to this powerful technique and will provide the definitive explanation to those who have been struggling to use them. 1558600210LangtextGame development is still in its infancy, but games are poised for a major evolution: Ready to move from mostly plot-driven stories to more character based ones. The problem is that the principles of sophisticated character design and interaction are not widely understood in the game development community. And gender and cultural issues within the game genre are growing in importance. Katherine Isbister has spent 10 years examining what makes interactions with computer characters useful and engaging to different audiences. The key is to understand what´s memorable, exciting, useful, and engaging to the participant about real-life social interactions, and applying that to character design. Game designers who create great characters often make use of these principles without realizing it. This book gives game design professionals and other designers a framework for how social roles and perceptual manipulations function, so that they are more aware of what they are doing when they design characters, and why it works.
The second edition of Statistics for Experimenters focuses on applications in the physical, engineering, biological, and social sciences. From the beginning, the book´s source of ideas is the scientific method itself and the need of the investigator to make his or her research as effective as possible through proper choice and conduct of experiments and appropriate analysis of data. After a problem is stated, appropriate statistical methods of design and analysis are discussed. And frequently, examples are presented for which standard mathematical assumptions are wrong, thus forcing the reader´s attention onto the essential precautions necessary in the conduct of the experiment to ensure valid conclusions. A Classic adapted to modern times Rewritten and updated, this new edition of Statistics for Experimenters adopts the same approaches as the landmark First Edition by teaching with examples, readily understood graphics, and the appropriate use of computers. Catalyzing innovation, problem solving, and discovery, the Second Edition provides experimenters with the scientific and statistical tools needed to maximize the knowledge gained from research data, illustrating how these tools may best be utilized during all stages of the investigative process. The authors´ practical approach starts with a problem that needs to be solved and then examines the appropriate statistical methods of design and analysis. Providing even greater accessibility for its users, the Second Edition is thoroughly revised and updated to reflect the changes in techniques and technologies since the publication of the classic First Edition. Among the new topics included are: * Graphical Analysis of Variance * Computer Analysis of Complex Designs * Simplification by transformation * Hands-on experimentation using Response Service Methods * Further development of robust product and process design using split plot arrangements and minimization of error transmission * Introduction to Process Control, Forecasting and Time Series * Illustrations demonstrating how multi-response problems can be solved using the concepts of active and inert factor spaces and canonical spaces * Bayesian approaches to model selection and sequential experimentation An appendix featuring Quaquaversal quotes from a variety of sources including noted statisticians and scientists to famous philosophers is provided to illustrate key concepts and enliven the learning process. All the computations in the Second Edition can be done utilizing the statistical language R. Functions for displaying ANOVA and lamba plots, Bayesian screening, and model building are all included and R packages are available online. All theses topics can also be applied utilizing easy-to-use commercial software packages. Complete with applications covering the physical, engineering, biological, and social sciences, Statistics for Experimenters is designed for individuals who must use statistical approaches to conduct an experiment, but do not necessarily have formal training in statistics. Experimenters need only a basic understanding of mathematics to master all the statistical methods presented. This text is an essential reference for all researchers and is a highly recommended course book for undergraduate and graduate students.
