I'm trying to flip a coloured rectangle. Is it possible to use the rotateTransition to do this?
I have tried the following code:
public void rotateField(){
RotateTransition rt = new RotateTransition(Duration.millis(3000), field[4][4]);
rt.setByAngle(360);
rt.setCycleCount(1);
rt.play();
}
However, this doesn't flip the rectangle, it just rotates it. I would like to actually flip the rectangle as you would flip a playing card.
Is it possible to use the rotateTransition class for this?
I like Sergey's solution, it is such a clever use of ScaleTransition and working in 2D means you don't need to deal with some of the complexities of 3D.
Here a couple of 3D rotation samples.
Rotates a 2D Node (an ImageView) round the Y axis (requires JavaFX 2.2 + 3D support).

rotator.play();
}
private Scene createScene(Node card) {
StackPane root = new StackPane();
root.getChildren().addAll(card);
Scene scene = new Scene(root, 600, 700, true, SceneAntialiasing.BALANCED);
scene.setCamera(new PerspectiveCamera());
return scene;
