In Detail
OpenSceneGraph is an open source 3D graphics application programming interface, used by application developers in fields such as visual simulation, computer games, virtual reality, scientific visualization, and modeling. Familiar with its concepts and APIs, and need to improve your knowledge? This book is here to help. With exactly 100 recipes, it will enrich your experience and take you to the next level.
OpenSceneGraph 3 Cookbook will escort you into the world of real-time 3D development with OpenSceneGraph, the world famous 3D graphics engine. The book assumes that you are already familiar with some basic concepts, and provides 100 vivid recipes to demonstrate how to utilize the API flexibly and how to implement some practical aspects.
The book is divided into 10 chapters, each of which focuses on one topic. Readers may start from any topic they are interested in.
The book includes customizing OpenSceneGraph, designing scene graph, geometry, scene navigation, animations, effects using fixed pipeline and shaders, managing mass data, and miscellaneous discussions. Every recipe will prove to be useful in a practical way or in research.
OpenSceneGraph 3 Cookbook gives you a wide insight about 3D programming using OpenSceneGraph, with a set of meaningful and interesting examples.
