JavaFX | Cylinder with examples


Cylinder is a part of JavaFX . Cylinder class is used to create a 3Dimensional cylinder of specified height and radius. The Cylinder is centered at origin.

The constructor for the class are

  1. Cylinder():Creates a new instance of Cylinder of radius of 1.0 and height of 2.0.
  2. Cylinder(double r, double h):Creates a new instance of Cylinder of a given radius and height.
  3. Cylinder(double r, double h, int div):Creates a new instance of Cylinder of a given radius and height and divisions

Commonly used methods

method explanantion
getHeight() returns the height of the cylinder
getRadius() returns the radius of the base of cylinder
setHeight(double v) sets the height of the cylinder
setRadius(double v) sets the radius of the cylinder


Java program to create a cylinder and add it to the stage

This program creates a Cylinder indicated by the name cylinder( the height, and radius is passed as arguments). The Cylinder 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 cylinder is attached.The group is attached to the scene. Finally, the show() method is called to display the final results.

Java program to create a cylinder and add a perspective camera to it

This program creates a Cylinder indicated by the name cylinder( the height and radius is passed as arguments). The Cylinder 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 cylinder is attached.The group is attached to the scene. Finally, the show() method is called to display the final results.A persepctive camera will be created and added to the scene to render the cylinder in 3D.
