I need help making 5 more objects and transformation methods.

here is my assignment:

Overview

In this project you will create a unique 3 scene composed of OpenGL graphic components using transformation methods.

Requirements:

1. Using Netbeans or Eclipse, develop a JOGL application that displays a unique 3D scene. The scene has the following specifications:

a. Size: 640x480

b. Includes at least 6 different shapes

c. Uses at least 6 different transformation methods

2. Use Java and JOGL for your implementation of OpenGL

3. All Java source code should be written using Google Java style guide.

4. Prepare, conduct and document a test plan verifying each method is functioning properly. (Hint: Using JUNIT tests are recommended)

here is my code:

/** * Use JOGL to draw a simple cube * with each face being a different color. Rotations * can be applied with the arrow keys, the page up * key, and the page down key. The home key will set * all rotations to 0. Initial rotations about the * x, y, and z axes are 15, -15, and 0. * * This program is meant as an example of using modeling * transforms, with glPushMatrix and glPopMatrix. * * Note that this program does not use lighting. */ public class UnlitCube extends GLJPanel implements GLEventListener, KeyListener { /** * A main routine to create and show a window that contains a * panel of type UnlitCube.
