Rotating Gears

The applet below is a sample distributed along with Java implementation of the OpenGL specifications. I modified the sample a little just to check that I understood how it works. When you drag the mouse the performance is really amazing. If this is not a good reason for inclusion of the applet here, then perhaps it may be used to demonstrate relevance of simple mathematics to gear switching.

If you were using a Java-capable browser, you would see very nice Rotating Gears instead of this paragraph.

This applet requires Sun's Java VM 2 which your browser may perceive as a popup. Which it is not. If you want to see the applet work, visit Sun's website at, download and install Java VM and enjoy the applet. In addition, you'll need the Java3D library available at

What if applet does not run?
