Problem drawing a Box

Engines, Libraries and Tools Java 3D
#1

I am new to J3D and cant get a basic Box drawn.
Right now I am just play with sample code and replacing the ColorCube constructor with the Box constructor wih no success.
It compiles and shows a black canvas, I made sure to add import com.sun.j3d.utils.geometry.Box;

Please set me right. What is wrong?

Here the code I am focusing on:
//Commented out-- //objRoot.addChild(new ColorCube(0.4));
//My Box code
objRoot.addChild(new Box());

public class HelloJava3Da extends Applet {
    public HelloJava3Da() {
        setLayout(new BorderLayout());
        GraphicsConfiguration config =
           SimpleUniverse.getPreferredConfiguration();

        Canvas3D canvas3D = new Canvas3D(config);
        add("Center", canvas3D);

        BranchGroup scene = createSceneGraph();

        // SimpleUniverse is a Convenience Utility class
        SimpleUniverse simpleU = new SimpleUniverse(canvas3D);

	// This will move the ViewPlatform back a bit so the
	// objects in the scene can be viewed.
        simpleU.getViewingPlatform().setNominalViewingTransform();

        simpleU.addBranchGraph(scene);
    } // end of HelloJava3Da (constructor)

     public BranchGroup createSceneGraph() {
	// Create the root of the branch graph
	BranchGroup objRoot = new BranchGroup();

       //Commented out-- //objRoot.addChild(new ColorCube(0.4));
       //My Box code
      objRoot.addChild(new Box());

	return objRoot;
    } // end of CreateSceneGraph method of HelloJava3Da

I am sure it is a simple mistake… ???

Box box = new Box();
box.setAppearance(new Appearance()); // Just using the defaults.
objRoot.addChild(box);

Thanks. It was the set appearance that i lacked.

I’m not use to needing soo many setters per object. :-\
