In this book, XNA expert Reimer Grootjans brings together a selection of the hottest quick-start recipes in XNA programming for the Xbox and Windows PC. Advanced XNA programmers, experienced coders new to games development, and even complete beginners will find XNA Game Programming Recipes an invaluable companion when building games for fun or as commercial products. Numerous problem-solving recipes cover topics from cameras and angles, to textures, models, and lighting and shadowing, and will get you over the common hurdles encountered in both 2D and 3D XNA application design.

Riemer Grootjans received his degree in electronic engineering with a specialization in informatics at the Vrije Universiteit Brussel in Belgium. He is a member of a research team working toward a Ph.D, and is responsible for visualization of 3D data. For several years, Riemer has been maintaining a web site with tutorials for DirectX. Since the early beta stages of XNA in 2006, he has ported all his content to XNA and is helping more than 1,000 people on their path to XNA success every day. In July 2007 and 2008, he received the Microsoft 'Most Valuable Professional' Award for his contributions to the XNA community.
