I recently reviewed a copy of The Blender Gamekit: Interactive 3D for Artists which was very informative when it came to 3D design. The book came with a CD that was the perfect guide that shows you some example games and shows some specific details on how features in those games work. The book was produced by The Blender Foundation was well as printed and distributed by No Starch Press.
Here is a brief description from the No Starch Press…
The Blender GameKit, 2nd Edition starts with an extensive section for people who are new to 3D—explaining all basic concepts—or new to Blender; with a full introduction to the interface. Then it shows in step-by-step tutorials the fun of creating models, adding motion to them, and how to turn them into simple games. Experienced 3D artists will appreciate the more complex game demos, the character animation tutorials, the introduction to Python, a tutorial with the Frankie character, and the advanced reference section.
The CDROM contains several playable and editable Blender game demos, created by renowned artists from the Blender community. It also contains all the files needed for the tutorials and Blender V2.48, for all platforms.
Be sure to pick yourself up a copy today and teach yourself some 3D design!
