* This program demonstrates the difference between Local Eye Lighting
* and Infinite Eye Lighting. To see the difference, you need to
* comment out the appropriate line in the code, recompile and rerun
* the application.
*
* This version of the program is different than the one used to
* generate images for the tutorial document. This this version
* both a directional and point light are included in the scene.
* the directional light is red, the point light is white. The spheres
* are blue (diffuse) with white specular material.
*
* The red specular reflections are from the directional light.
* The white specular reflections are from the point light.
* The blue diffuse reflection is from the directional light.
*
* This application (or a version of it) generated one or more
* of the images in Chapter 6 of Getting Started with the Java 3D API.
* The Java 3D Turtorial.
