Blender is an extremely complex program used for the even more complex task of producing high-quality 3D models and animations. As such, I can't cover every single feature and button in Blender. For a more comprehensive manual, refer to the excellent online documentation available through Blender's Web site at wiki.blender.org.
Because I want to bring you up to speed on working in 3D space with Blender so that you can start bringing your ideas to life as soon as possible, I focus on introducing you to the fundamental “Blender way” of working. Not only do I show you how something is done in Blender, but I also often take the time to explain why things are done a certain way. This approach should hopefully put you on the fast track to making awesome work and also allow you to figure out new parts of Blender on your own when you come across them.
Throughout the book, I refer to the Blender community. Blender's user community is probably one of its most valuable assets, and I would be remiss to neglect bringing it up. Not only do many members of the community create great work, but they also write new code for Blender, write and edit documentation, and help each other improve. And understand that when I make reference to the Blender community, I include you in that community as well. As of right now, you are a Blenderhead — a fellow Blender user and therefore a member of the Blender community.
Blender is a truly cross-platform program, running on Linux, Windows, Macintosh, ...
