I want to implement cel shading into my opengl game. I have only found a nehe tutorial that uses glaux (old as hell). I'm looking into it, but I wanna avoid the pain of learning how to translate those old glaux functions/variables. Is there any cel shading tutorial out there that uses glut/sdl?
You should search Toon Shading too.
For english readers, a short tutorial.
For french readers, there is a great tutorial.
Here's an article explaining all the processes behind it, but not actually giving code.
Or there's the fact you also asked this on SO too, which is wasting everybody's time.
