We'd like to first thank Don Burns and Robert Osfield for their creative efforts in giving birth to OpenSceneGraph, as well as thousands of members in the OSG core community, for their supports and contributions all the time.
Thanks again to Robert Osfield, a pure open source enthusiast and father of a happy family, for his tremendous passion in leading the development the OSG project for so many years (since 1999). He also took time out of his busy schedule to write the foreword for this book.
We must express our deep gratitude to Rakesh Shejwal, Usha Iyer, Leena Purkait, Priya Mukherji, and the entire Packt Publishing team for their talented work in producing yet another product, as well as Jean-Sébastien Guay and Cedric Pinson for reviewing the first drafts of the book and providing insightful feedback.
We would like to acknowledge John F. Richardson and Marek Teichmann, who announced the book at the OpenSceneGraph BOF at SIGGRAPH 2010. We also offer special thanks to Zhanying Wei, Xuexia Chen, Shixing Yang, Peng Xiao, Qingliang Liu, Su Jiang, and a number of other people who contributed to the completion of this book in different ways.
Finally, we owe the most sincere thanks to Paul Martz, who dedicates the first non-commercial book to OSG beginners all over the world and provides great help in supporting the publication of our past and current books.
