This Java applet illustrates a three dimensional graphics example: a rotating wireframe cube. There are four classes that are used. Here is the source code for the classes:

1. This class represents a point in three dimensional space: xyzpoint.java
2. This class represents a line connecting two points in three dimensional space: xyzline.java
3. This class represents a wireframe object as an array of xyzline objects: wirefr.java
4. Display a rotating wireframe cube: cube.java
