Back to the Fun Stuff: Going Beyond the Bouncy Square

Now we can go back to the example that was used in Chapter 1. Now that we're getting seriously 3D, several things will need to be added to handle the Z-dimension, including a larger dataset for the cube's geometry and color, methods of handing off that data to OpenGL, a more complex frustum definition, any face-culling techniques if needed, and rotations instead of just the translations.

Adding the Geometry

From Chapter 1, you'll remember the data as defined in Listing 3–1. First is the location of the four corners, the vertices, how the vertices connect together, and how they are colored.
