That's not even how anaglyph images work. If you look at that through your colored glasses you won't see a depth effect. You need to render the scene twice, once with a camera moved a little to the left and rotated to the right, and once with one moved a little to the right and rotated to the left. The amount of rotation defines the focal point; the rotation is important and in your current shader it is not present. Then you combine the red-channel of the left with the blue and green channel of the right image to the final color.
