程序实现思路: 在javafx中Node对象有一个effect属性，可以用于实现各种特效。PerspectiveTransform特效可以使Node对象实现透视变换。因此我们可以通过计算透视变换中每个点的位置来实现3D翻转特效。

实现步骤: 1、定义FlipView对象。包含以下属性:

//正面视图	public Node frontNode;	//反面视图	public Node backNode;	//是否翻转	boolean flipped = false;	//翻转角度	DoubleProperty time = new SimpleDoubleProperty(Math.PI / 2);	//正面翻转特效	PerspectiveTransform frontEffect = new PerspectiveTransform();	//反面翻转特效	PerspectiveTransform backEffect = new PerspectiveTransform();

 create方法返回需要显示的内容:

private void create() {		time.addListener(new ChangeListener() {			@Override			public void changed(ObservableValue
      arg0,					Number arg1, Number arg2) {				setPT(frontEffect, time.get());				setPT(backEffect, time.get());			}		});		anim.getKeyFrames().addAll(frame1, frame2);		backNode.visibleProperty().bind(				Bindings.when(time.lessThan(0)).then(true).otherwise(false));		frontNode.visibleProperty().bind(				Bindings.when(time.lessThan(0)).then(false).otherwise(true));		setPT(frontEffect, time.get());		setPT(backEffect, time.get());		frontNode.setEffect(frontEffect);		backNode.setEffect(backEffect);		getChildren().addAll(backNode, frontNode);	}

 以上代码需要注意的是: 随着time值的变化frontEffect和backEffect的值也会随着变换。 2、PerspectiveTransform特效的实现使用了Math.sin()和Math.cos()方法模拟3D角度变换。 具体实现如下:

private void setPT(PerspectiveTransform pt, double t) {		double width = 200;		double height = 200;		double radius = width / 2;		double back = height / 10;		pt.setUlx(radius - Math.sin(t) * radius);		pt.setUly(0 - Math.cos(t) * back);		pt.setUrx(radius + Math.sin(t) * radius);		pt.setUry(0 + Math.cos(t) * back);		pt.setLrx(radius + Math.sin(t) * radius);		pt.setLry(height - Math.cos(t) * back);		pt.setLlx(radius - Math.sin(t) * radius);		pt.setLly(height + Math.cos(t) * back);	}

 3、角度变换在1秒的时间内从3.14/2变换到-3.14/2。

KeyFrame frame1 = new KeyFrame(Duration.ZERO, new KeyValue(time,			Math.PI / 2, Interpolator.LINEAR));	KeyFrame frame2 = new KeyFrame(Duration.seconds(1),			new EventHandler() {				@Override				public void handle(ActionEvent event) {					flipped = !flipped;				}			}, new KeyValue(time, -Math.PI / 2, Interpolator.LINEAR));

 4、FlipView对象的创建:通过构造函数可以很方便的创建FlipView对象.

ImageView image1 = new ImageView(new Image(getClass()				.getResourceAsStream("lion1.png")));ImageView image2 = new ImageView(new Image(getClass()				.getResourceAsStream("lion2.png")));FlipView flip = new FlipView(image1, image2);
