I wanted to learn OpenGL more (I know generally how it works, but I can't write any usable program). However, every tutorial I've found (like NeHe, red book) is very old and teaches about 1.x. OpenGL 2.0 brigs GLSL, which totally changes the way you have to program. I know that probably such a great tutorial that teaches GLSL + GL3.x + VBO + etc doesn't exist... But maybe some sort of resource center that is oriented on newer OGL programming? Of cource I'm talking about HTTP and free web
Any help appreciated.
