This book features a novel geometric data structure for collision detection at haptic rates between arbitrary rigid objects. It offers a state of the art review of the current data structures for collision detection and presents new applications. Starting with novel algorithms for optimally updating bounding volume hierarchies of objects undergoing arbitrary deformations, the author presents a new data structure that allows, for the first time, the computation of the penetration volume. The penetration volume is related to the water displacement of the overlapping region, and thus corresponds to a physically motivated and continuous force. The practicability of the approaches used is shown by realizing new applications in the field of robotics and haptics, including a user study that evaluates the influence of the degrees of freedom in complex haptic interactions. New Geometric Data Structures for Collision Detection and Haptics closes by proposing an open source benchmarking suite that evaluates both the performance and the quality of the collision response in order to guarantee a fair comparison of different collision detection algorithms. Required in the fields of computer graphics, physically-based simulations, computer animations, robotics and haptics, collision detection is a fundamental problem that arises every time we interact with virtual objects. Some of the open challenges associated with collision detection include the handling of deformable objects, the stable computation of physically-plausible contact information, and the extremely high frequencies that are required for haptic rendering. New Geometric Data Structures for Collision Detection and Haptics presents new solutions to all of these challenges, and will prove to be a valuable resource for researchers and practitioners of collision detection in the haptics, robotics and computer graphics and animation domains.

§B§Die Herren der Ringe§§S§In den achtziger Jahren war er der "Herr der Boxringe" - Europameister, Weltmeister und derjenige, dem die deutsche Boxszene damals internationale Anerkennung verdankte: Rene Weller. Mit seinem engen Freund Max Herfert, ebenfalls Boxer aus Leidenschaft, hat er nun seine "Philosophie" zu Papier gebracht. Das Buch - für Anfänger und Fortgeschrittene gleichermaßen geeignet - widmet sich nach einer ausführlichen Unterweisung in die Grundlagen des Boxkampfes jenen Schlagkombinationen, die Wellers persönlichen Stil ausmachen. Beide Boxer wissen um die Probleme Lernender und bieten bewusst leicht verständliche Lösungen an, die sie mit zahlreichen Zeichnungen und Fotos veranschaulichen. Informationen über den Ablauf von Wettkämpfen, die richtige Ernährung, die mentale Einstellung und das Verhältnis zwischen Trainer und Boxer runden die Darstellung ab, die nicht nur Spezialisten, sondern ein breites Publikum anspricht.
