JavaFX | Sphere with examples

Last Updated : 22 Apr, 2021

Sphere is a part of JavaFX. Sphere class is used to create a 3 dimensional sphere with a specified radius . The sphere is centered at origin.
Sphere class inherits Shape3D class.
Constructor for the class are

Sphere(): creates a new sphere with radius 1.0
Sphere(double r): creates a new sphere with a given radius
Sphere(double r, int div): creates a new sphere with a given radius and number of divisions

Commonly used methods

method	explanation
getDivisions()	returns the number of divisions of the sphere
getRadius()	returns the radius of sphere
setRadius(double r)	sets the radius of the sphere to specified value

The following programs will illustrate the use of Sphere class

Java program to create sphere by passing the radius as arguments in constructor

This program creates a Sphere indicated by the name sphere( radius is passed as arguments). The Sphere will be created inside a scene, which in turn will be hosted inside a stage. The function setTitle() is used to provide title to the stage. Then a Group is created, and the sphere is attached.The group is attached to the scene. Finally, the show() method is called to display the final results.

Java

// Java program to create sphere by passing the radius
// as arguments in constructor
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.shape.DrawMode;
import javafx.scene.layout.*;
import javafx.event.ActionEvent;
import javafx.scene.shape.Sphere;
import javafx.scene.control.*;
import javafx.stage.Stage;
import javafx.scene.Group;
public class sphere_0 extends Application {

    // launch the application
    public void start(Stage stage)
    {
        // set title for the stage
        stage.setTitle("creating sphere");

        // create a sphere
        Sphere sphere = new Sphere(80.0f);

        // create a Group
        Group group = new Group(sphere);

        // translate the sphere to a position
        sphere.setTranslateX(100);
        sphere.setTranslateY(100);

        // create a scene
        Scene scene = new Scene(group, 500, 300);

        // set the scene
        stage.setScene(scene);

        stage.show();
    }

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

output:
