Hi,
For a long time I want to learn OpenGL, but I totally lost, they are many versions of OpenGL, I don’t find any tutorial for ‘LWJGL’ OpenGL, except of LWJGL wiki but he’s not really comprehensive(for a beginner).
People contradictory on many subjects.
I know LibGdx can be better for me, but I want to understand how it works, and try to make my own little game engine.
So, if anyone have a good website, or book or whatever that can help me, I’m present … 
Thank You
PS: Sorry for my english
