That's a good start -- thanks for the link I'll start there.

I suppose most of the confusion has to do with the plethora of OpenGL implementations and versions out there.  There always seems to be some fragment of knowledge missing out of each example.

It seems pretty apparent that the way to go is to follow the C-based tutorials and references and carefully trans-code them into Java, but before you can do that you have to have a JOGL scaffolding to build on.   Until you posted that link I hadn't found any example that uses this code:

     GL2ES2 gl = drawable.getGL().getGL2ES2();

There are a lot of things you have to understand to be able to understand that, and I have found now comprehensive reference that explains it.   I think I understand that now but it has been a twisty path.

Thanks for the help.
