JavaFX Cylinder

In general, a cylinder can be defined as a three dimensional solid object having two parallel circular basis connected by a curved surface. There are the two main parameters that describe a cylinder, namely height of the curved surface and the radius of the circular base.

The radius and the height of a cylinder are shown in the following image.

In JavaFX, the class javafx.scene.shape.Cylinder represents a cylinder. We just need to instantiate this class in order to create a cylinder.

Properties

The properties of the class along with the setter methods are described in the following table.

Property	Property	Setter Methods
height	It is a double type property. It represents the Z dimension of the Cylinder.	setHeight(double value)
radius	It is a double type property. It represents the radius of the Cylinder.	setRadius(double value)

Constructors

There are the three constructors in the class.

1. public Cylinder() : Creates the new instance with default parameters.
2. public Cylinder(double radius, double height) : Creates the new instance with the specified radius and height.
3. public Cylinder(double radius, double height, int divisions) : creates the new instance with the specified radius, height and divisions.

Example

package application; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.PerspectiveCamera; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Cylinder; import javafx.stage.Stage; public class CylinderExample extends Application{ @Override public void start(Stage primaryStage) throws Exception { // TODO Auto-generated method stub //creating cylinder Cylinder cyn = new Cylinder(); //setting the radius and height for the cylinder cyn.setRadius(80); cyn.setHeight(200); cyn.setTranslateX(300); cyn.setTranslateY(250); //setting camera PerspectiveCamera camera = new PerspectiveCamera(); camera.setTranslateX(100); camera.setTranslateY(100); camera.setTranslateZ(0); //setting group and stage Group root = new Group(); root.getChildren().addAll(cyn); Scene scene = new Scene(root,450,300,Color.LIMEGREEN); scene.setCamera(camera); primaryStage.setScene(scene); primaryStage.setTitle(“Cylinder Example”); primaryStage.show(); } public static void main(String[] args) { launch(args); } }
