JavaFX | Sphere with examples
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:
Java program to create a Sphere and add a perspective camera to render the 3D object
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.A perspective camera will be created and added to the scene to render the cylinder in 3D.
