Java3D in ein JPanel integrieren mit Netbeans 6.8

[Silentday]

Hallo Leute,

ich steh vor einem großen Problem. Ich will eine 3D Visualisierung, die von einem Kollegen implementiert wurde in meine GUI integrieren. Ziel ist es das ich sie in ein JPanel bekomme.

Die Visualisierung verwendet einen Graphen zur Darstellung von Beziehungen zwischen Personen mit Knoten und Kanten.

Die Visualisierung hatte er derweil als eigenständige Klasse (als Applet) geschrieben, doch nun soll sie halt in meine SWING - Oberfläche integriert werden.

Muss ich da vielleicht was mit einem AWT Canvas machen oder nur das JPanel erweitern oder ... ??? keine ahnung. habe shcon stunden mit der suche verbracht.

Ich verwende Netbeans 6.8 und habe nicht wirklich einen Plan von Java3D.

Der Code zum Graphen (Visualisierung) lautet:

package java3d;

Bitte um schnelle Hilfe da ich bis morgen dieses Problem gelöst haben muss

 

[Marco13]

Am Anfang vielleicht sowas in der Richtung...

    public static void main(String[] args)
    {
        SwingUtilities.invokeLater(new Runnable()
        {
            public void run()
            {
                JFrame frame = new JFrame();
                frame.getContentPane().setLayout(new BorderLayout());
                VisualFunctions v = new VisualFunctions();
                frame.getContentPane().add(v.getCanvas(), BorderLayout.CENTER);
                frame.setSize(500,500);
                frame.setVisible(true);
            }
        });
    }
    
    private Canvas3D canvas3D;
    
    public Canvas3D getCanvas()
    {
        return canvas3D;
    }
    
    public VisualFunctions()
    {
        GraphicsConfiguration config = SimpleUniverse
            .getPreferredConfiguration();
        canvas3D = new Canvas3D(config);

...

Swing und AWT (Canvas3D) mischen kann aber unerwünschte Effekte nach sich ziehen (Übermalen von Swing-Components und so...)

Hy danke Marco für die schnele Antwort!

ich bräuchte eher was in die richtung.

hier ist der Code von einem kleinen Fenster das aus einem Menü einem TexArea und einem JPanel bestet.

ich hätte die visualisierung (Java3d) gerne im JPanel
