# example of Billboard node
# Last Modified 17-Sept-97
# The example defines a red box inside a group. This box is at (0,0,0)
# and will be viewed from the defined Viewpoint position (see Viewpoint
# node below). Inside the Billboard node 2 others cubes are defined ( the
# green and blue ones). The billboard feature aligns both boxes to the
# viewer so that their sides can not be seen anymore.
