  //まずは、基礎フレームの設定。
  //============================================================================
  //メイン・ウィンドウ作成
  JFrame frame = new JFrame();
  //ウィンドウのサイズ設定
  frame.setSize(400,400);
  //ウィンドウのタイトル設定
  frame.setTitle("Polygon_test");
  //ウィンドウを閉じる動作の登録
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  //コンテントペインを作成
  JPanel cp = new JPanel();
  //コンテントペイン上のレイアウトは全て手動で行う
  cp.setLayout(null);
  //フレームに、コンテントペインを登録
  frame.add(cp);

  //============================================================================
  //次にJava3D関係の設定。
  //============================================================================
  //現在使用している画面の、ハードウェア情報を取得する
  GraphicsConfiguration g_config = SimpleUniverse.getPreferredConfiguration();
  //Cnavas3D_ViewChangeクラスを用意する（距離は40, マウス感度は0.1）
  Canvas3D_ViewChange canvas = new Canvas3D_ViewChange(40.0f, 0.1f, g_config);
  //3D表示領域の大きさを設定。今回はウィンドウいっぱいに表示する
  canvas.setBounds(0,0,400,400);
  //コンテントペインにCanvas3Dを登録
  cp.add(canvas);


  //============================================================================
  //3D空間を構築していきます
  //============================================================================
  //Canvas3DクラスのSimpleUniverseを利用。

  //座標軸クラスをインスタンス化
