OpenGL 3.0

• [ code (FR) ] Tutorials and C++ code to introduce OpenGL 3.0 using a Qt 5.0 window and CMake. The archive also contains assignement subjects (in French) with very detailed comments inlined in the code to learn step by step OpenGL functions. (taught at Master degree level)

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. For an introduction to the more recent pipeline: open.gl seems to be a good starting point.

Note: this course was designed for Master students.

The Bulwer-Lytton fiction contest is held ever year at San Jose State
Univ. by Professor Scott Rice. It is held in memory of Edward George
Earle Bulwer-Lytton (1803-1873), a rather prolific and popular (in his
time) novelist. He is best known today for having written "The Last
Days of Pompeii."

Whenever Snoopy starts typing his novel from the top of his doghouse,
beginning "It was a dark and stormy night..." he is borrowing from Lord
Bulwer-Lytton. This was the line that opened his novel, "Paul Clifford,"
written in 1830. The full line reveals why it is so bad:

It was a dark and stormy night; the rain fell in torrents -- except
at occasional intervals, when it was checked by a violent gust of
wind which swept up the streets (for it is in London that our scene
lies), rattling along the housetops, and fiercely agitating the scanty
flame of the lamps that struggled against the darkness.
