What are various 3D shapes provided by JavaFX?
In general, a 3D shape is a geometrical figure that can be drawn on the XYZ plane. These include a Cylinder, Sphere, and a Box.
The javafx.scene.shape.Shape3D package provides various classes each of them represents/defines a 3d geometrical object or, an operation on them. The class named Shape3D is the base class of all the 3-Dimensional shapes in JavaFX.
Following are various geometrical shapes that you can draw using JavaFX −
Cylinder − A cylinder is a closed solid that has two parallel (mostly circular) bases connected by a curved surface.
Sphere − A sphere is defined as the set of points that are all at the same distance r from a given point in a 3D space. This distance r is the radius of the sphere and the given point is the center of the sphere.
Box − A cuboid is a three-dimensional shape with a length (depth), width, and height.
To create a required shape, you need to −
Instantiate the respective class.
Set its properties.
Add the created object to Group.
Example
Following JavaFX Example demonstrates the creation of all the available 3D shapes −
import javafx.application.Application; import javafx.scene.Group; import javafx.scene.PerspectiveCamera; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.paint.PhongMaterial; import javafx.stage.Stage; import javafx.scene.shape.Box; import javafx.scene.shape.Cylinder; import javafx.scene.shape.Sphere; import javafx.scene.text.Font; import javafx.scene.text.FontPosture; import javafx.scene.text.FontWeight; import javafx.scene.text.Text; public class JavaFX3DShapes extends Application { public void start(Stage stage) { //Drawing a Box Box cube = new Box(100, 120, 100); //Setting color and translating the box PhongMaterial material = new PhongMaterial(); material.setDiffuseColor(Color.DARKRED); cube.setMaterial(material); cube.setTranslateX(30.0); cube.setTranslateY(180.0); cube.setTranslateZ(150.0); //Drawing a Cylinder Cylinder cylinder = new Cylinder(50, 150); //Setting the properties of the cylinder cylinder.setMaterial(material); cylinder.setTranslateX(250.0); cylinder.setTranslateY(180.0); cylinder.setTranslateZ(150.0); //Drawing a Sphere Sphere sphere = new Sphere(75); //Setting the properties of the sphere sphere.setMaterial(material); sphere.setTranslateX(480.0); sphere.setTranslateY(180.0); sphere.setTranslateZ(150.0); //Setting the perspective camera PerspectiveCamera cam = new PerspectiveCamera(); cam.setTranslateX(-50); cam.setTranslateY(50); cam.setTranslateZ(0); Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 15); Text label1 = new Text("Box"); label1.setFont(font); label1.setX(50); label1.setY(270); Text label2 = new Text("Cylinder"); label2.setFont(font); label2.setX(210); label2.setY(270); Text label3 = new Text("Sphere"); label3.setFont(font); label3.setX(400); label3.setY(270); //Setting the Scene Group root = new Group(cube, cylinder, sphere, label1,label2,label3); Scene scene = new Scene(root, 595, 300, Color.BEIGE); scene.setCamera(cam); stage.setTitle("Drawing 3D Shapes"); stage.setScene(scene); stage.show(); } public static void main(String args[]){ launch(args); } }
