JavaFX | Light.Point Class

Light.Point class is a part of JavaFX. Light.Point class represents a point light source in 3D space. Light.Point class extends the Light class.

Constructors of the class:

1. Point(): Creates a new Point Light object with default values.
2. Point(double x, double y, double z, Color color): Creates a new Point Light object with x, y, z and color values.

Commonly Used Methods:

Below programs illustrate the use of Light.point class:

1. Java Program to create a Point light and add it to a rectangle: In this program we will create a Rectangle named rectangle with specified height and width. We will also create a Light.Point object named light. We will set the x, y, z values using setX(), setY() and setZ() function. Now create a lighting object and add the light object to lighting using setLight() function. We will set the Lighting effect to the Rectangle and add it to the scene and add the scene to the stage and call the show function to display the results.

   
   

   
   
   

   // Java Program to create a Point light  // and add it to a rectangle import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.shape.Rectangle; import javafx.scene.control.*; import javafx.stage.Stage; import javafx.scene.Group; import javafx.scene.effect.Light.*; import javafx.scene.effect.*; import javafx.scene.paint.Color;    public class Point_1 extends Application {        // launch the application     public void start(Stage stage)     {            // set title for the stage         stage.setTitle("creating Light.Point");            // create point Light object         Light.Point light = new Light.Point();            // set coordinates         light.setX(100);         light.setY(100);         light.setZ(100);            // create a lighting         Lighting lighting = new Lighting();            // set Light of lighting         lighting.setLight(light);            // create a rectangle         Rectangle rect = new Rectangle(250, 250);            // set fill         rect.setFill(Color.WHITE);            // set effect         rect.setEffect(lighting);            // create a Group         Group group = new Group(rect);            // create a scene         Scene scene = new Scene(group, 500, 300);            // set the scene         stage.setScene(scene);            stage.show();     }        // Main Method     public static void main(String args[])     {            // launch the application         launch(args);     } }

   Output:

   

2. Java Program to create a Point light and add it to a rectangle and set the color of the light to red: In this program we will create a Rectangle named rectangle with specified height and width. We will also create a Light.Point object named light. Now pass the x, y, z and the color values as parameters of the constructor. We will create a lighting object and add the light object to lighting using setLight() function. We will set the Lighting effect to the Rectangle and add it to the scene and add the scene to the stage and call the show function to display the results.
