Written with a fast-paced but friendly and engaging approach, this Packt Beginner's Guide is designed to be placed alongside the computer as your guide and mentor. Step-by-step tutorials are bolstered by explanations of the reasoning behind what you are doing. You will quickly pick up the necessary skills, tips, and tricks for creating successful 3D graphics with practical examples that help you to learn by experiment and play. This book is intended for software developers who are new to OpenSceneGraph and considering using it in their applications. It is assumed that you have basic knowledge of C++ before using this book, especially the standard template library (STL) constructs, of which OSG makes extensive use. Some familiarity with design patterns as implemented in C++ is also useful, but is not required. You need to be familiar with OpenGL, the standard cross-platform low-level 3D graphics API. We'll meet some maths in the book—geometry and linear algebra—and familiarity with these topics will be great, but you don't need to be a maths whiz to use this book.
About the Authors
Rui Wang is a software engineer at the Chinese Academy of Surveying and Mapping and the manager of osgChina, the largest OSG discussion website in China. He is one of the most active members of the official OSG community, who contributes to the serialization I/O, GPU-based particle functionalities, BVH and animated GIF plugins, and other fixes and improvements to the OSG project. He translated Paul Martz's OpenSceneGraph Quick Start Guide into Chinese in 2008, and wrote his own Chinese book OpenSceneGraph Design and Implementation in 2009, cooperating with Xuelei Qian. He is also a novel writer and a guitar lover.
Xuelei Qian received his B.Sc. degree in Precision Instrument Engineering from Southeast University, Jiangsu, China, and his Ph.D. degree in applied graphic computing from the University of Derby, Derby, UK in 1998 and 2005, respectively. Upon completion of his Ph.D. degree, he worked as a postdoctoral research fellow in the Dept. of Precision Instrument and Mechanology at Tsinghua University and his current research interests include E-manufacturing, STEP-NC and intelligent CNC, and virtual reality engineering.
