Important

These tutorials are meant for OpenGL versions 1.x and 2.x. A lot of the information in these tutorials is outdated and either deprecated or removed in OpenGL 3.x and 4.x, so I have been writing some new tutorials on OpenGL 4.0. As you can see some of the tutorials here are (Version 2.0) which means they have been rewritten and include much more information, not only on OpenGL but explaining the fundamentals of the computer graphics behind the tutorials.
