I really want to explore the use of openGL particularly as it relates to making custom UI objects with JSUI. I am trying to learn as much about openGL as I can, but it seems like the standard has gone through several (big) changes. If I want to learn openGL best, to work with it in Max, should I learn 2.1, 3.3, 3.4 or 4?
Or does it even make a difference? i am just starting out and I do not know if I should be using tutorials relating to the newest openGL or not? Thanks.
