JavaFX: Lighting

The Lighting effect simulates a light source shining on the given content, which can be used to give flat objects a more realistic three-dimensional appearance.

 

Why lighting?

Makes scenes look like 3D.

 

Light class

Light class is an abstract base class for all light implementations.

 

Different types of Light implementations

JavaFX support 3 different types of lights.

a.   Distant light (Light.Distant)

b.   Point light (Light.Point) 

c. Spot light (Light.Spot)


Lighting class

Lighting an effect that simulates a light source shining on the given content, which can be used to give flat objects a more realistic, three-dimensional appearance.

 

You need to create a Lighting instance with specific Light instance and apply Lighting effect a node.

 

Example

Light.Distant distantLight = new Light.Distant();

distantLight.setAzimuth(160);

 

Lighting lighting = new Lighting(distantLight);

lighting.setSurfaceScale(10);

 

text1.setEffect(lighting);

 

Find the below working application.

lightingEffectDemo.fxml

import javafx.scene.*?>
import javafx.scene.shape.*?>
import javafx.scene.layout.*?>
import javafx.scene.text.*?>

Group xmlns:fx="http://javafx.com/fxml" fx:controller="com.sample.app.effects.controller.LightingController">

Text fx:id = "text1" text="With Light" fill="lightgreen"
style="-fx-font-weight: bold; -fx-font-size: 50; -fx-font-family: Verdana; -fx-font-style: italic"
stroke="darkblue" strokeWidth="2"
underline="true"
x="50" y = "100"/>

Text fx:id = "text2" text="Without Light" fill="lightgreen"
style="-fx-font-weight: bold; -fx-font-size: 50; -fx-font-family: Verdana; -fx-font-style: italic"
stroke="darkblue" strokeWidth="2"

}

}

LightingDemo.java

launch(args);

}

@Override
public void start(Stage primaryStage) throws Exception {

Parent root = (Parent) FXMLLoader.load(this.getClass().getResource(FXML_FILE));

Scene scene = new Scene(root, 600, 400, Color.WHITE);

primaryStage.setTitle(STAGE_TITLE);
primaryStage.setScene(scene);
primaryStage.show();
}

}
