Problem mit DirectX

[pria]

Moin,
ich wollt mal ein DirectX-Programm schreiben und hatte hier schonmal ein Thread für ein DirectX-Panel eröffnet. Hat alles soweit geklappt , wollte jetzt allerdings mal n 3D-Objekt rendern und wie es der Zufall so will , wird das nicht angezeigt. Ich hab dann nochmal versucht Text zu rendern und das klappt aber. Meine Frage ist , ob mir jemand sagen kann , woran das liegt?

        private Device m_device;
        private Panel devpanel;
        internal LightsCollection Lights
        {
            get { return m_device.Lights; }
        }
        private Mesh meshes;
        private Font[] renderTextStyle = new Font[0];
        private string[,] renderText = new string[0, 4];
        private Matrix World = new Matrix();

        internal Rendering(Panel devicepanel)
        {
            this.devpanel = devicepanel;
            initGFX();

        }

        internal void initGFX()
        {
            try
            {

                PresentParameters pp = new PresentParameters();

                pp.Windowed = true;
                pp.DeviceWindow = devpanel;
                pp.SwapEffect = SwapEffect.Copy;

                m_device = new Device(Manager.Adapters.Default.Adapter, DeviceType.Hardware, devpanel, CreateFlags.HardwareVertexProcessing, pp);

                //Vector3 size;
                //meshes = create3DText("Hallo", new System.Drawing.Font("Arial", 12), 0.001F, 0.5F, out size);
                meshes = Mesh.Box(m_device, 2.0f, 1.0f, 2.0f);
            }
            catch (DirectXException e)
            {
                MessageBox.Show(e.Message);
            }

        }

        internal void Render()
        {
            m_device.Clear(ClearFlags.Target,devpanel.BackColor, 0.0f, 0);
            m_device.BeginScene();
            // rendern
             //m_device.Transform.World = Matrix.Identity;
             meshes.DrawSubset(0);
             for (int i = 0; i < renderTextStyle.Length; i++)
              if (renderTextStyle[i] != null)
               renderTextStyle[i].DrawText(null, renderText[i, 0], new System.Drawing.Point(Convert.ToInt16(renderText[i, 1]), Convert.ToInt16(renderText[i, 2])), System.Drawing.Color.FromArgb(Convert.ToInt16(renderText[i, 3])));
            // @rendern
            m_device.EndScene();
            m_device.Present();

        }

Ich hab in meiner aufrufenden Klasse nurnoch eine Deklaration und einen Timer , der alle 100ms die Rendern-Methode aufruft.
