OpenGL 3.0
[ 
code (FR/EN) ] Tutorials and C++ code to introduce OpenGL 3.0 using a Qt 5.0 window and CMake. You'll also find assignement instructions (in French) with very detailed comments inlined in the code to learn step by step OpenGL functions. (usually taught to 4th year university students). Although you should not need them you can ask for answer sheets by email. Note all assignment were translated from French. Please ask for English translation if you think you want to try them. To dive deeper into OpenGL and graphic programming take also a look at open.gl or learnopengl.com.

OpenGL 2.1
This is an old tutorial mostly about the deprecated openGL 2.1. It can be useful to understand old projects (many are still using GL 2.1) and is easier to learn at first. But since you will have to learn openGL 3.0 at some point you might want to jump to it directly. Note that this course was designed for Master students.
