How to put a gradient background?

[sergicion]

I know I can put a color for the background with glClearColor(), but, how can I put a gradient?

Thanks a lot!!

The only way to make a gradient is to create a polygon that fills up the whole view and render it (well, you can also use a fullscreen image and blit it on the screen, but that would be slower). Just change the colors of the vertexes of the polygon and you have a nice gradient.

And a sun gradient? Like minecraft

Another way to do it, is to make the gradient image by yourself with a image editor software (easy done with photofiltre or photoshop), and draw a quad textured with this image, that fits your whole screen!  
To keep it in background you must draw it before all your other drawings.
