If you want your camera moved to the left, you move the whole world right. That's why you will notice the "-" sign in the translation vector where he used … WebeyeX, eyeY and eyeZ are (obviously) the camera position (which you should have already). center X, Y and Z are the positions of the object you want to focus on. upX, upY and upZ are the up vector's coordinates (I seriously have no idea why OpenGL needs this, but I won't argue). This should be 0, 1 and 0 respectively.
