Step 3 of the simple recipe is to create the content branch graph. A content branch graph is created in
Code Fragment 1-2. It is probably the simplest content branch graph possible. The content branch
created in Code Fragment 1-2 contains one static graphical object, a ColorCube. The ColorCube is
located at the origin of the virtual world coordinate system. With the given location and orientation of
the viewing direction and the cube, the cube appears as a rectangle when rendered. The image is shown
after all of the code for the program is presented, in Figure 1-12.
