Vollständig realistische Erfahrungen in einer virtuellen Welt anbieten: Darum geht es bei Immersiver Virtueller Realität. Das ausführliche Lehrbuch bietet Studierenden der Informatik, Medien-, Ingenieur- oder Sozialwissenschaften sowie Medienschaffenden und Anwendern immersiver Umgebungen ein anschauliches Nachschlagewerk zu einschlägigen Lehrveranstaltungen oder zum Selbststudium. Dabei adressiert das Buch alle Aspekte immersiver Medien, die für ein ganzheitliches Verständnis relevant sind: Die ersten Kapitel führen in die theoretischen Grundlagen ein. Diese behandeln die verschiedenen Ausprägungender Realität sowie das Metaversum als Zukunftsvision des Internets, geben einen historischen Überblick, beschreiben relevante Sinne und setzen sich mit Interaktion, Interface und Fortbewegung auseinander. Die darauffolgenden Kapitel veranschaulichen die zugrundeliegenden Technologien wie Sensorik, Tracking und Ausgabetechniken einschließlich Stereoskopie und kopfbezogener Übertragungsfunktion. Der letzte Teil des Buches gibt praxisnahe Einblicke in die unterschiedlichen Anwendungsbereiche: Unterhaltung, soziale Interaktion, Lehren und Lernen, Entwicklung sowie soziologische und medientheoretische Forschung.

This book presents the recent computational developments inspired by swarms in art known as swarm art and discusses applying swarm intelligence concepts in architecture. Non-human art is a great leap in the evolution of contemporary art, removing the requirement of an artist's production from the creative process. Furthermore, it is a critical declaration in opposition to the anthropomorphic vision which is so destructive for all other life forms and the planet's ecology. When accepted and integrated into human culture, non-human art done by artificial systems or machines boosts creativity and stimulates innovative fusions. We analyze 120 swarm systems with unique and diverse conceptual contexts, agent design, and audience engagement that can be utilized as inspiration for future projects or to design new swarm algorithms by artists, architects, or computer scientists.

Computergrafik umfasst die Erzeugung und Darstellung von einfachen Grafikelementen und Bildern bis hin zur Virtual Reality. Die Anwendung dieser Techniken profitiert von einem soliden Verstandnis der entsprechenden Grundlagen. Das erfolgreiche Buch von Prof. Klawonn, das jetzt bereits in der dritten Auflage vorliegt, vermittelt genau das - verstandlich und nachvollziehbar. Prof. Klawonn erlautert die wesentlichen Konzepte an konkreten Beispielen und bedient sich dabei der einfachen Sprachmittel der Javaprogrammierung. Die Umsetzung erfolgt praktisch mit Java 2D und Java 3D. Auch zur dritten Auflage gibt es wieder einen umfangreichen Online-Service mit Beispielprogrammen, Aufgaben und Losungen, Folien und farbigen Illustrationen.

This book constitutes the joint refereed proceedings of the 14th International Workshop on Approximation Algorithms for Combinatorial Optimization Problems, APPROX 2011, and the 15th International Workshop on Randomization and Computation, RANDOM 2011, held in Princeton, New Jersey, USA, in August 2011. The volume presents 29 revised full papers of the APPROX 2011 workshop, selected from 66 submissions, and 29 revised full papers of the RANDOM 2011 workshop, selected from 64 submissions. They were carefully reviewed and selected for inclusion in the book. In addition two abstracts of invited talks are included.APPROX focuses on algorithmic and complexity issues surrounding the development of efficient approximate solutions to computationally difficult problems. RANDOM is concerned with applications of randomness to computational and combinatorial problems.

Gain skills in illustration and logo manipulation that will enhance your designs and make them more appealing--either in your portfolio or for your client's next graphic project.As Adobe's Photoshop and Illustrator have evolved, new and unique features have been added to these programs that offer different options for warping and distorting graphics and shapes. For the beginner and intermediate student or graphic artist, choosing or knowing which distort or warp tool to use among so many available can become overwhelming and confusing.This book primarily focuses on teaching how to work with various warping tools and effect filters in Illustrator, though you will also be using or comparing graphics from Adobe Photoshop. Knowing how to work between these two applications is a crucial part of understanding how to successfully manipulate your designs. In Illustrator, you'll see how to alter vector graphics, and learn how to do this with your Layers panel in various non-destructive ways. Some of the tools mentioned in this book will be familiar to you, as you may have used them frequently. However, others are well hidden, are new, or perhaps you have never considered that you could use that tool, dialog box, or filter effect to warp or distort.  You Will:Become proficient in using the warping and distorting tools and effects in IllustratorDiscover how to add perspective to your design or make them look three dimensional Work with the Appearance panel, Graphic Styles, and SymbolsCombine older tools and newer, enhanced ones

Sir William Rowan Hamilton was a genius, and will be remembered for his significant contributions to physics and mathematics. The Hamiltonian, which is used in quantum physics to describe the total energy of a system, would have been a major achievement for anyone, but Hamilton also invented quaternions, which paved the way for modern vector analysis. Quaternions are one of the most documented inventions in the history of mathematics, and this book is about their invention, and how they are used to rotate vectors about an arbitrary axis. Apart from introducing the reader to the features of quaternions and their associated algebra, the book provides valuable historical facts that bring the subject alive. Quaternions for Computer Graphics introduces the reader to quaternion algebra by describing concepts of sets, groups, fields and rings. It also includes chapters on imaginary quantities, complex numbers and the complex plane, which are essential to understanding quaternions. The book contains many illustrations and worked examples, which make it essential reading for students, academics, researchers and professional practitioners.
