The following transitions fall into this category: FadeTransition, FillTransition, and StrokeTransition.
The FillTransition transition makes a smooth change between two colors:
// chapter5/transitions/ColorTransitionsDemo.javaShape circle = new Circle(50, 150, 50);FillTransition ft = new FillTransition(Duration.seconds(3), circle, Color.RED, Color.BLUE);ft.play();
Intermediate values are calculated based on RGB and opacity numerical components of the Color through a special interpolator.
To make the Animation API aware of the interpolator support, the Color implements an Interpolatable interface, which you can use for your own components as well:
public interface Interpolatable<T> { public T interpolate(T endValue, ...
