ColorCube is a utility class found in the com.sun.j3d.utils.geometry package that defines the
geometry and colors of a cube centered at the origin with different colors on each face. The default
ColorCube object is in a cube that is 2 meters high, wide and deep. If a non-rotated cube is placed at the
origin (as in HelloJava3Da), the red face will be visual from the nominal viewing location. Other colors
are blue, magenta, yellow, green, and cyan.
