• Sommario/riassunto: Make motion capture part of your graphics and effects arsenal. This introduction to motion capture principles and techniques delivers a working understanding of today's state-of-the-art systems and workflows without the arcane pseudocodes and equations. Learn about the alternative systems, how they have evolved, and how they are typically used, as well as tried-and-true workflows that you can put to work for optimal effect. Demo files and tutorials provided on the companion CD deliver first-hand experience with some of the core processes.

• Sommario/riassunto: In dieser Biographie lernt der Leser neben der wissenschaftlichen auch die menschliche Seite des August Wilhelm Hofmann anlässlich seines 200. Geburtstag kennen. Anhand seiner zahlreichen Briefe gelingt es, einen tiefen Einblick in die Lebenswelt eines Wissenschaftlers im 19. Jahrhundert sowohl in London als auch in Berlin zu gewinnen. Interessant ist dabei die Nähe zu den Königshäusern, sei es Königin Victoria in England und später Kaiser Wilhelm I. und besonders Viktoria von Preussen "Vicky". Erstaunlich sind auch die für die damalige Zeit sehr weiten Reisen von Hofmann mit den vielen Erlebnissen, die ihn nach Ägypten und auch nach Nordamerika führten. Der Fachwelt ist Hofmann u. a. durch die Synthese von Anilinfarbstoffen wie Rosanilin und "Hofmanns Violette" bekannt, aber auch als Gründungspräsident der Deutschen Chemischen Gesellschaft, und jeder Schüler kennt heute den Wasserzersetzungsapparat nach Hofmann. -- (from back cover)
