There is a lot of information about OpenGL on the net, but they always start with, and are based on something like windows programming. I really don't care about any OS specific programming stuff because I have taught myself SDL. Are there any OpenGL tutorials/articles that concern using it with SDL?

Most of the tutorials at NeHe contain SDL ports.

well. not really. theres only one thing that differs from other opengl tutorials: the screen setup.

instead of os specific stuff, you have this:

SDL_GL_SetAttribute( SDL_GL_RED_SIZE, 8 );SDL_GL_SetAttribute( SDL_GL_GREEN_SIZE, 8 );SDL_GL_SetAttribute( SDL_GL_BLUE_SIZE, 8 );SDL_GL_SetAttribute( SDL_GL_ALPHA_SIZE, 8 );SDL_GL_SetAttribute( SDL_GL_DEPTH_SIZE, 24 );SDL_GL_SetAttribute( SDL_GL_DOUBLEBUFFER, 1 );    SDL_Surface *screen = SDL_SetVideoMode( 800, 600, 32, SDL_OPENGL);

after that, all open gl stuff is the same...

and you can still use sdl for stuff( like loading textures ), provided you dont try to blit to or read from the screen...

You'll obviously also need to replace the keyboard/mouse controls with SDL code, but you should be able to do that.

libsdl.org's doc project provides some sample code for setup and use with OpenGL:

Skimming over it might be helpful.

I found this:

Just thought I'd post it here in case someone else
is looking for the same thing.

Thanks for everyone who replied!
