graphicsConfiguration - a valid GraphicsConfiguration object that will be used to create the canvas. This object should not be null and should be created using a GraphicsConfigTemplate3D or the getPreferredConfiguration() method of the SimpleUniverse utility. For backward compatibility with earlier versions of Java 3D, a null or default GraphicsConfiguration will still work when used to create a Canvas3D on the default screen, but an error message will be printed. A NullPointerException or IllegalArgumentException will be thrown in a subsequent release.
