In this JavaFX source code example, we will see how to use the JavaFX Lighting effect with an example. 

Lighting simulates a light source shining on the given content, which can be used to give flat objects a more realistic, three-dimensional appearance. The setAzimuth method of the Light source sets the azimuth—the direction angle for the light source.

JavaFX Lighting Example

The example applies a Lighting effect on a Text control. The azimuth of the light is controlled by a Slider.

    private void initUI(Stage stage) {

        VBox root = new VBox(30);
        root.setPadding(new Insets(10));

        SimpleDoubleProperty azimuth = new SimpleDoubleProperty(0);

        Light.Distant light = new Light.Distant();
        light.setAzimuth(0);

        Lighting lighting = new Lighting(light);
        lighting.setSurfaceScale(5.0);

        Text text = new Text();
        text.setText("Source Code Examples");
        text.setFill(Color.LIGHTSKYBLUE);
        text.setFont(Font.font(null, FontWeight.BOLD, 25));

        Slider slider = new Slider(1, 360, 0);
        azimuth.bind(slider.valueProperty());

        slider.valueProperty().addListener(event -> {
            light.setAzimuth(azimuth.get());
            lighting.setLight(light);
            text.setEffect(lighting);
        });

        text.setEffect(lighting);

        root.getChildren().addAll(slider, text);

        Scene scene = new Scene(root, 300, 250, Color.WHITESMOKE);

        stage.setTitle("Lighting");
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
