Set background color to a texture

Question

So in openGL when I call glClearColor() is there a way to set the background color to a texture instead of setting it just to a static color? Or is there another method which can do that besides glClearColor()?

Answer 1

You cannot clear the screen to a texture. You can:

• Draw a textured quad the size of the screen.

• Blit a texture from an FBO onto the screen.

Either one will work.
