Hi Everyone!
this is my first code with j3d..

import java.applet.*;
import java.awt.*;
import java.awt.GraphicsConfiguration;
import javax.media.j3d.BranchGroup;
import javax.media.j3d.Canvas3D;
import javax.media.j3d.Transform3D;
import javax.media.j3d.TransformGroup;

import com.sun.j3d.utils.applet.MainFrame;
import com.sun.j3d.utils.geometry.ColorCube;
import com.sun.j3d.utils.universe.SimpleUniverse;



public class HelloJava3D extends Applet {

        public HelloJava3D() {
                setLayout(new BorderLayout());
                Transform3D t = new Transform3D();
                GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration();
                Canvas3D canvas3D = new Canvas3D(config);
                add("Center",canvas3D);
                BranchGroup scene = createSceneGraph();
                scene.compile();
               
                SimpleUniverse simpleU = new SimpleUniverse(canvas3D);
                simpleU.getViewingPlatform().setNominalViewingTransform();
                simpleU.addBranchGraph(scene);
        }
       
        public BranchGroup createSceneGraph() {
                BranchGroup node = new BranchGroup();
                TransformGroup TG = createSubGraph();
                node.addChild(TG);
                return node;
        }
       
        public TransformGroup createSubGraph() {
                TransformGroup transform = new TransformGroup();
                transform.addChild(new ColorCube(0.3));
                return transform;
        }
       
        public static void main(String args[]) {
                new MainFrame(new HelloJava3D(), 1024, 768);
        }
}
