How about creating some very cool 3D graphics applications closer to reality? Using Java 3D API one can create 3D graphics applications which are closer to reality. Java 3D is developed under the Java Community Process and runs on top of OpenGL. Offering 3D sound support it even sums up graphic programming using real, object oriented concept. Here the graphic objects are set in a scene graph and then the scene graph is handled for rendering to Java 3D and you don't have to make any efforts for writing any form of code to display data. My friend Peter has written a very good post about how graphic applications can be created using Java 3D. Hopefully you will like it.
