Is there a way to use pixel and vertex shaders in SDL 1.2.* or 1.3?

If you use OpenGL, sure. Otherwise, there is no guarantee what kind of
video backend you are using, so no.On Fri, Sep 18, 2009 at 10:55 AM, Cleber Tavares Jr. wrote:

You can pick the video driver by using SDL_VideoInit() and SDL_VideoQuit().
Like so:

int main(int, char**) {
SDL_Init(0);
SDL_VideoInit(“opengl”, 0);

/* … */

SDL_VideoQuit();
SDL_Quit();
}

You can find a more complete example here:

use SDL_OPENGL with SDL_SetVideoMode() in 1.2.
look around on http://nehe.gamedev.net/ to figure out how.
