In Chapter 2, we talked about 2D coordinate systems, including a special case of such systems: the screen coordinate system. When dealing with 3D coordinate systems, however, a lot more is involved with defining a 3D virtual object and transforming such an object into a 2D representation on the screen.
This chapter covers the basics of creating 3D games. First, you'll learn the fundamental concepts, and then you'll see how to apply them in a simple XNA project. This will prepare you for creating a complete 3D game in the next chapters.
Note XNA 3.0 currently does not support creating 3D games for Zunes.
When dealing with three Cartesian dimensions, two types of coordinate ...
