Processing with OpenGL in Eclipse
First, if you haven't, please read the Processing in Eclipse tutorial. This only has the additional information for using OPENGL in your application.
A couple notes about step 1. First, you do not have to copy the files into your project if you don't want to, you can always point to them in the Processing folder. However, if you move Processing, your application will break. In addition, by copying the files into the project directory, they will be included when you share it via CVS, and this is a good thing. Oh, you may want to consider copying all of these files into a folder called "opengl", rather than just dumping them in the project root directory.
You are all set! Just make sure you include:
as well as
in your code.
A project example with all of this set up for you in in the Examples CVS.
