如何设置Canvas3D背景颜色？

Question

我有一个用于绘制三维对象的Canvas3D类的应用程序。画布背景默认为黑色。我想改变它，但我不知道如何。我从互联网上找到了一段代码，但它不起作用。这里是代码：

 setLayout(new BorderLayout()); 
    GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration(); 
    canvas = new Canvas3D(config); 


    JPanel centerPanel = new JPanel(new GridLayout(1, 1)); 
    centerPanel.setBorder(BorderFactory.createLineBorder(Color.black)); 
    centerPanel.add(canvas); 

    universe = new SimpleUniverse(canvas); 

    Background newBk = new Background(new Color3f(Color.WHITE)); 
    newBk.setApplicationBounds(new BoundingSphere(new Point3d(0f,0f,0f), 100)); 
    canvas.getGraphicsContext3D().setBackground(newBk); 

你对这个问题有帮助吗？

在此先感谢。

Background background = new Background(new Color3f(1f,0,0)); 
BoundingSphere sphere = new BoundingSphere(new Point3d(0,0,0), 100000); 
background.setApplicationBounds(sphere); 
viewingPlatform.addChild(background);
