It was really an excing journey. I owe these people in my endeavour to write this book and I'd like to take this opportunity to express my gratude. Thanks to Nikolaus 'niko' Gebhardt and Ambiera e.U. for iniang this wonderful Irrlicht engine project and making it open-source, sharing with the community, Chrisan Stenho for reviewing the book and giving lots of useful feedback and all the folks from the Irrlicht forum. And the following people from Packt Publishing; Newton Sequeira (Author Relaon) for contacng me about this opportunity to write a book on Irrlicht, Usha (Acquision Editor), Maitreya Bhakal (Development Editor), and Ashwin Shey (Project Manager) for taking this project into reality, Michelle Quadros (Project Coordinator) for working and coordinang with me along the way, chapter-by-chapter, and Snehal Gawde (Technical Editor) for making sure everything ts together. I'd like to thank my big brother and my parents, who've been supporng me all these years. Without all of your support I wouldn't have been here today. And nally a big thank to my wife, Muriel. If she hadn't let me sit in front of my computer for hours, late nights, and weekends, wring this book, it wouldn't have been possible. Thank you for all your support. I love you. www.it-ebooks.info Johannes Stein is an independent game developer and former student of the university of Augsburg, Germany. He started showing an interest in computer science at the early age of twelve and has expanded his knowledge ever since. Aer learning Visual Basic and Delphi, he got into C/C++ and C#, while he learned Objecve-C and JavaScript, in the last few years. He specializes on cross-plaorm development, which means soware that runs on Windows, Linux, and Mac OS X for example. Apart from cross-plaorm development, he has developed mobile games and web applicaons using the latest technologies such as HTML5 and CSS3. On several occasions, he worked as a freelance journalist and reported from yearly events such as the gamescom in Cologne. Working on a book was a completely new and excing experience for me and rst of all I would like to thank everyone who had the paence to put up with me and helped me during the process. I would like to thank my parents who helped trying to movate me when I was feeling overwhelmed and frustrated. A special thanks goes to my father. I would also like to thank Nikolaus Gebhardt and Chrisan Stehno, who have not only been technical reviewers of this book, but shaped the Irrlicht engine into what it is now. And last, but not least I would like to thank everyone at Packt Publishing, who made this book possible and a simple "Thank you" does not cover how grateful I am. www.it-ebooks.info About the Reviewer Chrisan Stehno has been in touch with Irrlicht since 2004. Being a researcher at that me, he led a group of students to develop a 3D visualizaon tool. Since 2006, he has been part of the development team. Today he is responsible for the general coordinaon of the project and its development. When it comes down to coding, he likes working on the video drivers, but does the bug hunng in all parts of the engine. In real life, Chrisan is married (longer with his wife than with Irrlicht) and has two children. He is the founder and general manager of a small company, developing embedded systems and soware for industrial use. www.it-ebooks.info www.PacktPub.com Support les, eBooks, discount offers and more You might want to visit www.PacktPub.com for support les and downloads related to your book.
