Hello! I am new to SDL and just got a simple platform game with wall jumping and music to run:

I have spent a lot of time trying to figure out how to implement an OpenGL Shader into this game. I use SDL_Surfaces rendered with an SDL_Renderer. I have an OpenGL context successfully initialized in my SDL program, and my question is: How do I set up OpenGL fragment shaders so that they will shade what SDL renders?

My plan is to use a "God Ray" fragment shader, like the one used here.
