So I've been trying to learn some OpenGL for java and following along the tutorials, but I've run across my frist discrepency between the new and old versions of JOGL i think. The tuorial imports javax.media.opengl.* when I had been importing net.java.games.jogl. What is the difference between the two? Which one is newer? Also this is the error I am getting setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //only three JOGL lines of code ... and here they are GLCapabilities glcaps = new GLCapabilities(); GLCanvas glcanvas = GLDrawableFactory.getFactory().createGLCanvas(glcaps); glcanvas.addGLEventListener(new SimpleGLEventListener()); //add the GLCanvas just like we would any Component getContentPane().add(glcanvas, BorderLayout.CENTER); setSize(500, 300); //center the JFrame on the screen centerWindow(this); It says it can't find createGLCanvas in the javax.media.opengl pakcage.

javax.media.opengl.* is the newer one, I think javax.media.opengl is from JOGL 1.1, while net.java.games.jogl is from JOGL 1.0. There are a few differences between them, you you may want to check out the documentation for the newer one.

That's probably because there is no such thing as createGLCanvas(caps) in GLDrawableFactory. I think that may be something from JOGL 1.0. As of the version I have (1.1.1), you can directly instantiate a GLCanvas with GLCapabilities via its contructor.
